In the art design below, the combined area of the 5 square tiles and the green frame is 256 cm. The frame is of uniform width. To the nearest tenth, what is the side length x of each square tile?

4.7 cm

Step-by-step explanation:

Because I used a calculator lol

I hope this helps!! Let me know if it’s wrong!

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
