Question

A vertical pillar stands on the plain ground and is surmounted by a flagstaff of height 5 m. From a point on the ground, the angle of elevation of the bottom of the flagstaff is 45⁰ and that of the top of the flagstaff is 60⁰. Find the height of the pillar. (Use V3 = 1.732)
​

Answer 1

Answer:

Hey mate here is the answer

Step-by-step explanation:

tan 60° = AB /AP

√3. 5/AP

AP . 5/√3

5 . (1.732) = 8.66 m

suppose DB = x m

AD . (5+x) m

.tan 45° = AP/AP = 5+x/5√3

1 = 5+x/5√3

x = 5 (√3-1)

5 (1.732) - 5. ( √3 = 1.732)

= 8.66 -5

= 3.66

ANS - HEIGHT OF THE PILLAR IS 3.66 m
