Answer:
56 deg
Step-by-step explanation:
All internal angles of a triangle add up to 180 degrees
hence,
∠O + ∠R + ∠F = 180
x + (x+43) + (x-31) = 180
x + x+43 + x -31 = 180
3x+ 12 = 180
3x = 180 - 12 = 168
x = 168/3 = 56 deg
- Hypotenuse=H=9ft
- Base=B=2ft
Apply Pythagorean theorem
- P²=H²-B²
- P²=9²-2²
- P²=81-4
- P²=77
- P=√77
