Question

Determine the value of x in the triangle shown.

Question 2 options:

180°


45°


135°


90°

Answer 1

135

Explanation:

When there's a completely straight line the angle is 180 and when u have a angle already there you subtract 180 from the angle in this case 180-45=135

Answer 2

135

Explanation:

Hello There!

The angle that has a measure of 45° and x are supplementary angles meaning that the sum of the two angles is 180

so x can be found by subtracting the given angle (45 in this case) from 180

180 - 45 = 135

so x = 135
