If you diagonally slice the board, you get a right angle, which pyth thm can be used. side2 x side2 = diagonal2

34squared + 34squared = x (diagonal) squared
1156 + 1156 = x squared
2312 = x squared
x = 48.0832611207
so just correct it to the closest as 48 inches

Answer:

QR ≈ 16.2 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan62° = $\frac{opposite}{adjacent}$ = $\frac{QR}{RP}$ = $\frac{QR}{8.6}$ ( multiply both sides by 8.6 )

8.6 × tan62° = QR , then

QR ≈ 16.2 ft ( to the nearest tenth )
