Answer:

d. 60

Step-by-step explanation:

$(2x + 30) \degree = (4x - 90) \degree \\ (exterior \: alternate \: \angle s) \\ \\ 2x + 30 = 4x - 90 \\ \\ 30 + 90 = 4x - 2x \\ \\ 120 = 2x \\ \\ x = \frac{120}{2} \\ \\ x = 60$

How can I find the unknown side lengths when given the area or circumference of a figure?

ad-work [718]

Answer:

Set up the area/circumference equations using x as the unknown variable. Then, solve for that variable and apply the correct unit.

Step-by-step explanation:

For example,

Find the side length of a square with an area of 49 square centimeters.

Since $area=s^{2}$ , i can write $49=s^2\\then take the square root of each side to solve for s.\\s=\sqrt{49} \\s=7 centimeters$
