Question

Find the value of x.

Answer 1

Answer:

75

Step-by-step explanation:

Answer 2

Answer:

x = 140°

Step-by-step explanation:

Given angles: 30, x, x

Other 2 base angles=

180-70=110

180-60=120

Total sum of interior angles of a polygon = (n-2) 180°

n, number of sides = 5

Total sum= (5-2) 180°

= 540

So,

540= 30+2x+110+120

2x = 540 - 260 = 280

x = 280/2 = 140°
