Answer:

Explanation:

this has a bunch of "implied" things that you're supposed to know. one is that all the way around a circle is 360° two is that if you know the angle on the interior.. that is also the arc length.. so knowing those things we can say

360 = 54 + 2x + 21 + 5x + 6 + 90

put like terms together

360 = 171 + 7x

189 = 7x

27 = x

Answer:

x = 27

Explanation:

A circle adds up to 360 degrees. So we make this equation:

2x+21 + 5x+6 + 54 + 90 = 360

Combine like terms:

7x + 171 = 360

Subtract both sides by 171

7x = 189

Divide both sides by 7

x = 27
