Answer: 57.8512 feet (approx)
Step-by-step explanation:
Let h be the height of the stone face.
The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°
⇒ The distance of the base of the stone face from the base of the mountain =
The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,
Therefore,
The distance of the top of the stone face from the base of the mountain = (h + 487.055694898) feet
By the trigonometry,
Therefore, the height of the stone face is 57.8512 feet (approx).
