Question

find the angle and measure x in rhe following figuers​

Answer 1

Step-by-step explanation:

70°+x=180°( linear pair)

x=180°-70°

x=110°

60°+x=180°(linear pair)

x=180°-60°

x=120°

n=5

(angle sum property of polygon)=

(n-2)×180°

(5-2)×180°

3×180°

540°

30°+x+110°+120°+x=540°

260°+2x=540°

2x=540°-260°

2x=280°

x=280/2

x=140°
