Find the values of x and y.<br> No calculator needed.<br> Leave ✓ as a part of your answer.
valentina_108 [34]

Answer:

y=6 x=8.49

Step-by-step explanation:

Since angles p and r are 45deg QP and QR are the same length.

the pythagorean theorem states that a^2+b^2=c^2.

so 6^2+6^2=72

the square root of 72 is 8.49.

so x or c = 8.49
