If two angle measurements are 53° and 70,° what must the third angle measurement equal to form a triangle?Please help please?

Answer:

x = 63.5 degrees

Step-by-step explanation:

use sine:

sine = [tex]\frac{opposite}{hypotenuse}[/tex]

sine x = [tex]\frac{17}{19}[/tex]

sine x = 0.8947

sine-1 of 0.8947 = 63.4699

x = 63.4699

round to the nearest tenth:

x = 63.5

Answer:

108

Step-by-step explanation:

Given:

The given equation is

[tex]2x^3-3x^2+18x-27=0[/tex]

To find:

All the real solutions.

Solution:

We have,

[tex]2x^3-3x^2+18x-27=0[/tex]

It can be written as

[tex]x^2(2x-3)+9(2x-3)=0[/tex]

[tex](2x-3)(x^2+9)=0[/tex]

Using zero product property, we get

[tex](2x-3)=0[/tex] and [tex](x^2+9)=0[/tex]

[tex]2x=3[/tex] and [tex]x^2=-9[/tex]

[tex]x=\dfrac{3}{2}[/tex] and [tex]x=\pm\sqrt{-9}[/tex]

We know that [tex]x=\pm\sqrt{-9}[/tex] is an imaginary number because there is a negative sign under the square root.

Therefore, [tex]x=\dfrac{3}{2}[/tex] is the only real solution of the given equation.

The answer is A

Step-by-step explanation:

Start at 12 and add 6 every year:

12 + 6 = 18

18 + 6 = 24

Answer:

Step-by-step explanation:

Given the length and width of a square to be 12

If the of the square is dilated by a factor of 1, this means that the value will be multiplied by 1 as shown;

New width = Old width * 1

New Width = 12 * 1

New width = 12

Hence the width of the new image will also be 12

Answer:

#25: 0.023 < 22%

#29: 7/8, 0.88, 90%

Step-by-step explanation:

#25: Use this trick whenever converting decimals into percent. Move the decimal point two spaces to the right. Example: 0.01 = 1%

#29: Divide 7 by 8 for 7/8 and convert the decimal into a percent. Do the same with 0.88. Then just list these measures on a number line :D

Answer:

x = 9

Step-by-step explanation:

Sum of exterior angles = 360

8x +14x +7x +11x = 360

              40x     = 360

                  x   = 360/40

x = 9

Answer:

The average distance between Earth and Pluto is same as average distance of Pluto from the Sun. This is 0.000628 light years, nearly.

Explanation:

The average distance obetween two planets is nearly the average distance of the outer planet from the Sun. Earth is inner to Pluto. Average Sun-Pluto distance = 5906.4 million km. Divide by 149597870 to get distance in Au. Further divide by 62900 to get distance in ly.

Answer:

2x+154       or       2(x+77)

Step-by-step explanation:

This is an expression as there is no equal sign. So you can't solve for x

Answer:

[tex]Area=\frac{ab}{2} \\\\area=\frac{9.5.23}{2} \\\\answer=108.8 yd^{2}[/tex]

Step-by-step explanation:

I hope this helps ^_^

The area of the triangle is 108.7 square yards.

Let a, b, and c is the sides of the triangle.

The area of the triangle is given as

S = (a + b + c) / 2

[tex]\rm A = \sqrt{s(s - a)(s - b)(s -c )}[/tex]

The third side of the triangle will be

c² = a² + b² - 2ab cos θ

c² = 9.5² + 23² - 2 × 9.5 × 23 × cos 85°

c² = 619.25 - 38.09

c² = 581.16

 c = 24.11 yd

Then the area of the triangle will be

S = (9.5 + 23 + 24.11) / 2

S = 56.61 / 2

S = 28.3

Then the area will be

[tex]\rm A = \sqrt{28.3(28.3 - 24.11)(28.3 - 23)(28.3 - 9.5)}[/tex]

Simplify the expression, then the value will be

A = √11815.01

A = 108.7 square yd

The area of the triangle is 108.7 square yards.
