Answer:
The elevation of Mt. Wilson is 16,160.10 ft
Step-by-step explanation:
Let
x-----> represent the elevation of Mt. Wilson
y ----> represent the elevation of Snow Crest
we know that
y=x+11,990.21 ----> linear equation that represent this situation
we have that
y=28,150.31 ft ----> see the attached figure
substitute in the linear equation and solve for x
28,150.31=x+11,990.21
x=28,150.31-11,990.21=16,160.10 ft
