PLEASE HELP ME IM SO CONFUSED

Answer 1

x+158+124+120+146+102=360

x+86+140+138+59=300

x+121+96+162+101+90=360

x+2x+143+152+116+125+139+140=480

Answer 2

Ok

Explanation:

I don't feel like using my calculator rn but I can tell you how to do it. So, there is a formula to calculate interior angle sum of a polygon. It is
`180(n-2)`. Here, n is the number of sides. For example, a square has 4 sides, and you plug in 4 in that formula to get 2*180° or 360°. So, for 15, since there are6 sides, the total angle sum inside that polygon is 180(6-2) which is 720. Then, do 720 minus the rest of the angles to find x.
