Question

From the top of tower, 100 m high, a man observes two cars on the opposite sides of the tower with the angles of depression 60° & 45°respectively. Find the distance between the cars​

Answer 1

Answer:

273.2m

Step-by-step explanation:

Let the height of the tower be AD=100m

Tan 45°=BD/AD

》1=BD/100

》100m=BD

Tan 60°=CD/AD

》root 3 =CD/100

》100×root 3=CD

》100×1.732=CD (VALUE OF ROOT 3= 1.732)

》173.2=CD

Therefore, BC=BD+DC

》BC=100+173.2

》BC=273.2m(Ans)
