SOLUTION: As part of a surveying problem, a laser beam ("L") is targeted from the ground to a point on a building (point "P")60 meters above ground. Find the lenght of the laser beam ("LP")

Question 195810: As part of a surveying problem, a laser beam ("L") is targeted from the ground to a point on a building (point "P")60 meters above ground. Find the lenght of the laser beam ("LP") and find the distance the laser is positioned from the building along the ground. The ground point is ("B"). The angle of the laser beam is 55*(angle LB)

Let us see the Laser Beam pointing to the building:

BY Trigo Function:

, Length of Laser beam

Also,

, Distance of ground point to the building

Or by Pyth Theorem:
