Question

What is the value of x in triangle PQR below?
86
94
132
142

Answer 1

I got answer 94. You have to add up given degrees and subtract from 180°.

Answer 2

x = 94°

Second option is correct.

Explanation:

We will use below properties to find the value of x.

The sum of interior angles of triangle is 180 degrees.

Thus, we have

∠P +∠Q + ∠R = 180°

Substituting the known values and solve the equation for x

x + 38° + 48° = 180°

x + 86° = 180°

x = 180°- 86°

x = 94°

Second option is correct.
