Homework Statement
A building is 400 ft tall and has suffered damage from a recent earthquake. If a surveyor is stationed 150 ft away, sets a zero angle on the bottom corner of the building, and turns the angle shown to the top of the building; what is the angle at which the building is leaning with respect to vertical?
Homework Equations
I feel like I know what to do, but would like confirmation from the forum please.
The Attempt at a Solution
sin(70)/400 = sinC/150
sinC=[150*sin(70)]/400
C=arcsin([150*sin(70)]/400)~=20.6332
1807020.6332=89.3668
Therefore, Beta = 89.3668
