Question

What is the value of x? Help asap please​

Answer 1

x = 30

Explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

100° is an exterior angle of the triangle, then

x + 70 = 100 ( subtract 70 from both sides )

x = 30

Answer 2

x = 30

Explanation:

A triangle's angles add up to 180

Also, angles on a straight line add up to 180

180-100 = 80

80+70=150

180-150=30
