A pillar is fixed at one of the corners of a square meadow. The length of each edge of the meadow is 30m and the angle of elevation of the top of the pillar from the opposite comer is found 60°. Find the height of the pillar.
(A) 93.49 m (B) 83.48 m (C) 69.93 m (D) 73.48m​

Respuesta :

Answer:

D. 73.48 m.

Step-by-step explanation:

The diagonal distance across the meadow

= √(30^2+30^2)

= √1800

tan 60 = h / length of the diagonal           (where h = height of the pillar).

h = √1800 * tan 60

= 73.48 m

The required height of the pillar if length of each edge of the meadow is 30m and the angle of elevation of 60 degrees is 73.48m

Angle of elevation and depression

The angle situated below the pillar is known as  the angle of elevation

Determine the diagonal distance

The diagonal distance across the meadow is calculated using the Pythagoras theorem:

l = √(30^2+30^2)
l = √1800

Determine the required height of the pillar using the SOH CAH TOA

tan 60 = h/l        

where h = height of the pillar

h = √1800 * tan 60

h  = 73.48 m

Hence the required height of the pillar if length of each edge of the meadow is 30m and the angle of elevation of the top of the pillar from the opposite comer of 60 degrees is 73.48m
