Question

(↓) 28 Find the value of z. Then find the angle measures of the polygon. + 120° 100° 120° 120° Sum of angle measures: 720° (x + 10)°​

Answer 1

x = 125, Angles are 120°, 100°, 120°, 135°, 120°, 125°

Explanation:

`120+100+120+x+10+120+x=720 \\ \\ 470+2x=720 \\ \\ 2x=250 \\ \\ x=125 \\ \\ \implies x+10=135`
