In the figure shown, the measure of angle PRS is how many ..

Hello,

I see someone else posted this question but there was no response to it.

The question is: In the figure shown, the measure of angle PRS is how many degrees greater than the measure of the angle PQR?

1) The measure of angle QPR is 30 degrees.
2) The sum of the measures of angles PQR and PRQ is 150 degrees.

The figure shows right triangle PSQ (angle S = 90 degrees). Within this triangle is a second right triangle PSR.

Answer is D, but I don't understand why.

From Statement 1:
Angle QPR = 30 as shown.

Now, 30 + x + y = 90
and , x + z = 90

subtracting the 2 above, gives z-y=30 (Remember, we have to find the difference of the angles, not the actual values of each of the angles)

Statement 2 is same as Statement 1.
