In ΔPQR, find the measure of ∡ P. Triangle PQR where angle Q is a right angle. QR measures 33 point 8. PR measures 57 point 6. M
Degger [83]
<span>ΔPQR is a right triangle
∡Q is a right angle.             ⇒⇒⇒ ∡Q = 90°
QR measures 33 point 8   ⇒⇒⇒ QR = 33.8 ⇒ leg of the triangle
PR measures 57 point 6   ⇒⇒⇒ PR = 57.6  ⇒ hypotenuse of the triangle

we can find ∡P using sin function
sin P = QR/PR = 33.8/57.6 = 0.5868
∴ ∡P = sin^{-1} 0.5868 ≈ 35.93°</span>
