I wish I could help but it looks hard
Answer:
None
Step-by-step explanation:
The angle of elevation from point C to point A is 
<em><u>Solution:</u></em>
Given that we have to find the angle of elevation from point C to Point A
Given in figure that, angle A = 
Given is a right angled triangle ABC where angle B = 
We have to find angle C
The angle sum property of a triangle states that the angles of a triangle always add up to 180°
Therefore, in given triangle ABC
angle A + angle B + angle C = 180


Therefore angle C = 
Answer:
B
