We are given with two equations and is asked to determine the solution of the system of linear equation. via elimination, we add the two equations to eliminate 3x, this means y should be equal to 9 and from the first equation, x should also be equal to 9, too

Answer:
the height of the building is 86.6m
Step-by-step explanation:
In the right triangle, the height which we are looking for is the opposite side, since it is opposite to the angle 60°
Now we need to find the height of the building
tanθ = Opposite side/Adjacent side
tan 60° = Opp side/Adj side
1.7321 = Opp side/50
1.7321 x 50 = Opp side
Opp side = 50 x 1.7321
Opp side = 86.6 m
Therefore, the height of the building is 86.6m.
