</span><span>we set in a point M and P. We both points by a simple and we extend it for the third quarter of the system. Compass measure the distance from the point M to the point P.

Answer:
- y = 242.4
- x = 437.3
First find the inner angle:
- 90° - 29°
- 61°
[ given hypotenuse = 500 ft ]
using sine rule:
using pythagoras theorem:
- a² + b² = c²
- y² + (437.3)² = 500²
- y = √58760.1
- y = 242.4
