Find a possible solution to the equation cos(x+2) = sin(3x)
A. x=0.5
B. x=1
C. x=22
D. x=44
Answer: C. x=22
Step-by-step explanation:
cos(22+2)= 0.913545457
sin(3*22)= 0.913545457
So, cos(x+2)=sin(3x)

The three side lengths of a triangle are given. Which triangle is a right triangle?
A. Triangle 1:13−−−√, 6, 7
B. Triangle 2: 7, 8, 13
C. Triangle 3: 10, 11, 12
D. Triangle 4:10−−−√, 9, 8
Answer:
i am assuming "13----√" means "√13" ect. I am also assuming that the first 2 values are legs and the final is the hypotenuse.
the answer is then "A"
Step-by-step explanation:
The triangle whose sides are √13, 6, and 7, is a right triangle.
What is the right triangle?A right triangle is defined as a triangle with one right angle or two perpendicular sides. The longest side of a right triangle is called the hypotenuse.
Pythagorean Theorem :The square on the hypotenuse is equal to the total of the squares on the legs of a right triangle.
Mathematically, let r be the length of the hypotenuse of a right triangle. Again let p, q be the lengths of other sides of this triangle. By the Pythagorean Theorem,
r² = p² + q².
How to solve this problem?We just check which triangle's sides follow the above theorem.
Option A (Triangle with sides √13, 6, and 7 ):
13 + 36 = 49
i.e. (√13)² + 6² = 7²
This triangle's sides follow the Pythagorean Theorem.
So, the triangle with sides √13, 6, and 7 is a right triangle.
Option B (Triangle with sides 7, 8, and 13 ):
49 + 64 ≠ 169
i.e. 7² + 8² ≠ 13²
This triangle's sides do not follow the Pythagorean Theorem.
So, the triangle with sides 7, 8, and 13 is not a right triangle.
Option C (Triangle with sides 10, 11, and 12 ):
100 + 121 ≠ 144
i.e. 10² + 11² ≠ 12²
This triangle's sides do not follow the Pythagorean Theorem.
So, the triangle with sides 10, 11, and 12 is not a right triangle.
Option D (Triangle with sides √10, 9, and 8 ):
10 + 64 ≠ 81
i.e. (√10)² + 8² ≠ 9²
This triangle's sides do not follow the Pythagorean Theorem.
So, the triangle with sides √10, 9, and 8 is not a right triangle.
Therefore the triangle whose sides are √13, 6, and 7, is a right triangle. So, option A is correct.

Answer:
angle BAD = 180 -2x
angle BCD = x given
angle BCD is an inscribed angle
angle DOB = 2 (angle BCD)
angle BAD = 180 -angle DOB 2 tangent theorem
Step-by-step explanation:
Answer:
[tex] m\angle BAD= (180 - 2x)\degree [/tex]
Step-by-step explanation:
[tex] m\widehat {BD} =2\times m\angle BCD[/tex]
(By inscribed angle theorem)
[tex] m\widehat {BD} =2x\degree [/tex]
[tex] m\widehat {BCD} =360\degree - m\widehat {BD}[/tex]
(By arc sum property of a circle)

1. Add the same number to both the numerator and the denominator of
the fraction 7/17, to change it to 3/5.
Answer:
8
Step-by-step explanation:
Let x be the number added to both numerator and denominator.
Initial fraction=7/17
After adding x to both the numerator and the denominator
Then ,we get fraction=3/5
We have to find the value of x.
According to question
[tex]\frac{7+x}{17+x}=\frac{3}{5}[/tex]

Answer:
1 17/42.
Step-by-step explanation:
Find the common denominator, which is 42.
So change -4 1/6 to -4 7/42.
And change 5 4/7 to 5 24/52.
So add -4 7/42 + 5 24/52 and you'll get: 1 17/42.

Solve the two-step inequality and match the answer to the graph
Answer:
(see below; answers at the bottom)
Step-by-step explanation:
-4x + 7 ≥ 27
-4x ≥ 20
-x ≥ 5
Whenever you multiply or divide by a negative number in an inequality, flip the sign:
x ≤ -5
x/1 - 9 < -10
x - 9 < -10
x < -1
3x - 10 < -25
3x < -15
x < -5
5 (x - 2) > -15
Use Distributive Property:
5x - 10 > -15
5x > -5
x > -1
A) x < -5
So, A) 3x - 10 < -25.
B) x ≤ -5
So, B) -4x + 7 ≥ 27.
C) x < -1
So, C) x/1 - 9 < -10.
D) x > -1
So, D) 5 (x - 2) > -15.
Please Help!!!!!! Use what you've learned today about the sum of the interior angles of triangles and quadrilaterals to determine the measure of ALL unknown angles in the figure below.
Answer:
m = 116
x = 24
y = 76
z = 40
Step-by-step explanation:
For startes the interior angles of triangles always add up to 180 degrees.
That means....
73 + 83 + x = 180
z + m + x = 180
z + y + 64 = 180
Another important fact is that two angles that are intersected by a line in the case 64 and m always add up to 180 degrees.
So m + 64 = 180
Let's start with 73 + 83 + x = 180
If you add 73 and 83 you get 156
x + 156 = 180 then subtract 156 from both sides and
x = 24
Then use m + 64 = 180 subtract 64 from both sides and
m = 116
z + m + x = 180 become
z + 116 + 24 = 180
Add 116 and 24 and you get 140
z + 140 = 180 subtract 140 from both sides and
z = 40
Check to make sure m + x + z = 180
24 + 40 + 116 = 180
z + y + 64 = 180 becomes
y + 40 + 64 = 180
40 + 64 = 104 so
y + 104 = 180 subtract 104 from both sides and
y = 76
Congratulations you have found all of the angles!

Find the slope!! Please
Answer:
The slope is -(1/3)
Step-by-step explanation:
For every 3rd step, the y-value decreases by 1 and the line intersects the y-axis in (0,1).
This observation yields the following equation for your line:
f(x) = y = -(1/3)x + 1
Therefore, the slope is -(1/3).

Answer:
1. 3(x-4)-9= 3
3x-12-9=3
3x-21=3
3x=24
x=8
2. x=6
3. x=8
4. x=2
Answer:
Miscellaneous
Step-by-step explanation:
1. Distribute and simplify to get: 3x-12-9 = -3
Then combine like terms to get 3x-21 = -3
Add 21 on both side sto get 3x = 18
divide 3 on both sides to get x=6
2. x+5 = 11
Subtract 5 from both sides to get x = 6
3. 2x-3 = 13
Add 3 to both sides to get 2x = 16
Divide 2 from both sides to get x =8
4. 4(x+2) = 16
Distribute to get 4x+8 = 16
Subtract 8 from both sides to get 4x = 8
Divide 4 from both sides to get x=2

I’m thinking of a number. When you multiply it by 3 and subtract 10 you will get a number less than 5. Form an inequality and solve it to describe the range of possible numbers
Answer:
[tex]3x-10<5\\x<5[/tex]
Step-by-step explanation:
Let x be equal to the number.
We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:
[tex]3x-10<5[/tex]
To find the range of possible values, we must solve the inequality and isolate x.
[tex]3x-10<5[/tex]
Add 10 to both sides
[tex]3x-10+10<5+10\\3x<15[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}<\frac{15}{3}\\x<5[/tex]
I hope this helps!
