Question

What is the measure of X?

Answer 1

The answer is B.

Explanation:

Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :

`60 + 80 + x = 180`

`140 + x = 180`

`x = 180 - 140`

`x = 40`

Answer 2

X = 40°

Explanation:

angleZ + angleY + angleX = 180° (Angle sum property)

80° + 60° + X° = 180°

140° + X° = 180°

X° = 180° - 140°

X° = 40°
