Zamir needs to determine the height of the building
What’s the Height “A”
What’s Height “B”
What’s the Height of “X”
PLEASE
Answers
Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = [tex]\frac{CD}{CE}[/tex]
CD = CE × [tex]\frac{1}{2}[/tex]
CD = [tex]\frac{29}{2}[/tex]
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft

What is the measure of the missing angle
Answers
Answer:
41°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let x be the missing angle, then sum the angles and equate to 180°, that is
87° + 52° + x = 180°
139° + x = 180° ( subtract 139° from both sides )
x = 41°
need help with questions 15 and 16 please
Answers
Answer:
#15: y = -5x -4
#16: y = 2/5x -4
Step-by-step explanation:
Lets start with #15:
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx -4
Pick another point and substitute its x and y values in this equation.
I chose (-1,1) and substituted as 1 = m(-1) -4
Isolate m:
1 + 4 = -m - 4 + 4
5 = -m
m = -5
The Equation in Slope Intercept Form is y = -5x -4
Let's do #16.
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx - 4
Pick another point and substitute its x and y values in this equation.
I used Fractional Points as Whole ones were not seen.
I chose (5/2,-3) and substituted as -3 = m(5/2) - 4
Isolate m:
-3 + 4 = 5m/2 - 4 + 4
1= 5m/2
m=2/5
The Equation in Slope Intercept Form is y = 2/5x - 4

Which statement is true about the following pair of rectangles?
Two rectangles are shown. To the left, a larger rectangle has a lower side labeled 60 centimeters and a left side labeled 30 centimeters. To the right, a smaller rectangle has an upper side labeled 6 centimeters and a right side labeled 3 centimeters.
A. They are not similar because Start Fraction 6 over 60 End Fraction≠ Start Fraction 30 over 3 End Fraction.
B. They are not similar because Start Fraction 30 over 3 End Fraction = Start Fraction 60 over 6 End Fraction.
C. They are not similar because Start Fraction 3 over 6 End Fraction ≠ Start Fraction 30 over 60 End Fraction.
D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.
Answers
Answer:
Option D
Step-by-step explanation:
the height of the first rectangle ( 30 ) over the height of the other rectangle ( 3 ) is 30/3 and equals 10
the length of the first rectangle ( 60 ) over the length of the second rectangle ( 6 ) is 60/6 and equals 10
the ratio of the sides of both rectangles are equivalent therefore the are similar

x-5=-y
3x-10=2y
Answers
Answer:
(4,1)
Step-by-step explanation:
Multiply the first equation by -3
(x-5=-y)*-3 = -3x+15=3y
Then combine like terms with the new equation and the second equation
(-3x+15=3y) + (3x-10=2y) = 5=5y
Divide 5 by both sides
1=y
Plug in 1 for y in an equation. Doesn’t matter which one and solve
x-5=-(1)
Distribute the negative sign to the 1
x-5=-1
Add 5 to both sides
x=4
X-5= -y
-X+5=y
-4+5=y
1=y
3X-10=2(-2+5)
3X-10= -2X+10
3X+2X=10+10
5x=20
X=4

pls help solve :)
Answers
Answer:eorder the terms:
-6 + n = 2n + -1n
Combine like terms: 2n + -1n = 1n
-6 + n = 1n
Solving
-6 + n = 1n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-1n' to each side of the equation.
-6 + n + -1n = 1n + -1n
Combine like terms: n + -1n = 0
-6 + 0 = 1n + -1n
-6 = 1n + -1n
Combine like terms: 1n + -1n = 0
-6 = 0
Add '6' to each side of the equation.
-6 + 6 = 0 + 6
Combine like terms: -6 + 6 = 0
0 = 0 + 6
Combine like terms: 0 + 6 = 6
0 = 6
Simplifying
0 = 6
Combine like terms: 0 + -6 = -6
-6 = 6 + -6
Combine like terms: 6 + -6 = 0
-6 = 0
Step-by-step explanation:
Answer:
-6 = 0n
Step-by-step explanation:
n - 6 = 2n - n

If 1432x-3 = 143x+1, then...
Answers
Answer: x= 4/1289 not sure if this was what you were looking for.
Step-by-step explanation:
Step 1: Subtract 143x from both sides.
1432x−3−143x=143x+1−143x
1289x−3=1
Step 2: Add 3 to both sides.
1289x−3+3=1+3
1289x=4
Step 3: Divide both sides by 1289.
1289x/1289 = 4/1289
x= 4/1289

Area of sector ≈ 15.6π (nearest tenth)
Step-by-step explanation:
Given:
radius = 5 cm
Central angle in radians = ∅ = 5π/4
Required:
Area of the sector
Solution:
Area of sector = ½*r²*∅
Plug in the values into the formula
Area of sector = ½*5²*5π/4
= ½*25*5π/4
= 12.5*5π/4
= (12.5*5π)/4
Area of sector = 15.625π ≈ 15.6π (nearest tenth)
