In right triangle PQR, m∠Q = 90° and sin R=5/13

1 answer:

5 0

Answer:

Step-by-step explanation:

Given

sinR = $\frac{5}{13}$ = $\frac{opposite}{hypotenuse}$

This is a 5- 12- 13 triangle with legs PQ = 5, QR = 12, hypotenuse PR = 13

cosR = $\frac{adjacent}{hypotenuse}$ = $\frac{QR}{PR}$ = $\frac{12}{13}$
