**Applications of Trigonometry Heights and Distances cbse ncert solutions class 10 Chapter 9 Exercise 9.1 Question 4**

**4.** The angle of elevation of the top of tower from a point on the ground, which is 30 m away from the foot of the tower, is 30. Find the height of the tower.

**Solution:**

The distance of point B from the foot of the tower (BC) = 30 m

We want to find height of tower AC

m

Therefore, Height of tower AC = m
