A pillar of height 243 ft casts a shadow of 342 ft long. Find the measure of the angle of elevation of the sun.
ans= 35 degree
Solution:
Step 1 :Length of the pillar, a = 243 ft.Step
2 :Length of the shadow, b = 342 ft.Step
3 :∠ACB is the angle of elevation of the sun.Step
4 :In right triangle ABC, tan C = 243342Step
5 :tan C = 0.710526Step 6 :∠C = 35°Step 7 :So, angle of elevation of the sun is 35°
