What is the measure of ∠x?

Answer:
We know that 48 + x = 90 degrees since we know PQS is a right triangle.
Therefor, if we subtract 48 from both sides we will get x.
90 - 48 = 42
Angle x is 42.
These angles are complimentary. What this means is that the sum is equal to 90 degrees. With this knowledge you can make a formula like so...
48 + x = 90
Solve for x by subtracting 48 to both sides
48 - 48 + x = 90 - 48
x = 42
Hope this helped!
