here is your answer mate.
in triangle ABC
angle ABC + angleBAC + angleACB = 180 Degrees. (angle sum property of triangle)
90 + 58 + angle ACB = 180 degree.
148 + angle ACB = 180 degree.
angle ACB = 180 - 148
angle ACB = 32 degree
the angle of elevation is 32 degrees
Option B. y = 3 (one-third) Superscript x is the function that is graphed in this question.
<h3>How to solve the problem</h3>
We have exponential functions to be of the form abˣ
This can be written in the form of f(x) = 
So it crosses through the point (0, 3).
From the way that the curve passes through the circle, we can see that the it is said to pass through at (0, 3) and approaches y = 0 in quadrant 1
Hence this would put our answer to be y = 3 (one-third) Superscript x

I guess you are asking the value of the Angle x, if so
it's equal to 180°-31° ==> mes angle x =149°
