Answer:
x =-2.1
Step-by-step explanation:
X/2+10=8.95
Subtract 10 from each side
X/2+10-10=8.95 -10
x/2 =-1.05
Multiply each side by 2
x/2*2 =-1.05*2
x =-2.1
0,-2

By using trigonometric relations, we will see that the angle of elevation must be 55°.

How to find the angle of elevation?</h3>
We can see this as a right triangle, where one cathetus measures 1250ft (altitude) and the other cathetus measures 875ft.
The angle of elevation is the angle such that the adjacent cathetus is the one measuring 875ft.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus)
tan(a) = 1250ft/875ft
To find the angle of elevation, we can use the inverse tangent function:
a = Atan(1250ft/875ft) = 55°
The angle of elevation must be 55 degrees.
