Question

The measure of PQR is 90°. Find the value of x.

Answer 1

18 degrees

Explanation:

Since the measure of PQR is 90 degrees, the two angles contained in it must add up to 90 degrees. Therefore:

19+2x+35=90

Combine like terms:

2x+54=90

Subtract 54 from both sides:

2x=36

Divide both sides by 2:

x=18
