TRIGONOMETRY
Answer:
QR = 11.9
PR = 15
m∠P = 53
Explanation:
QR & PR:
I am learning geometry right now, and haven't gotten to trigonometry yet, so I used a website named - www.omnicalculator.com - and I plugged in the information. I did round them to the nearest tenth in the end.
m∠P:
Triangles equal up to 180, and the square is 90, and the other angle is 37. If you do the math, 180 - (90 + 37) = 53.
