Question

The roof of a building is 16m high. A rope is tied from the roof to a peg on the ground 12m away from the wall of the building. What is the length of the rope? pls pls help

Answer 1

Answer:

The whole figure is a Right angled triangle..

H is 16 m and base is 12 m.

By Pythagoras theorem,

(Hypotenuse)2 = H^2+Base^2

Then, 16^2+ 12^2 = 256+144= 400

then hypotenuse= ✓400= 20

Your answer is 20m

Step-by-step explanation:

Hope it helps.

Answer 2

Answer:

H² = B² + P²

H² = 12² + 16²

H² = 144 + 256

H² = 400

H = √400

H = 20 m

So, Length is 20 m
