$x + 4 = 48$

Subtract sides 4

$x +4 - 4 = 48 - 4$

$x = 44°$

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

DerKrebs [107]

For this question, set up an equation. 60 times what decimal is 27?

60x=60

x=0.45

Convert this decimal to a percentage by multiplying it by 100:

45%

For this question, set up an equation. 55% (or 0.55) times what number equals 22?

0.55x=22

*Divide both sides by 0.55*

x=40

Hope this helps!!
