Answer 2

Given : A flag pole 5 m high casts a shadow 12 m long.

To Find  : the distance of the top of the pole from the far end of the shadow  

1️⃣ 17 m

2️⃣ 7 m

3️⃣ 15 m

4️⃣ 13 m

Solution:

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.

Base = 12 m

Height = 5 m

distance of the top of the pole from the far end of the shadow.* = √5² + 12²

= √25 + 144

= √169

=13

the distance of the top of the pole from the far end of the shadow = 13 m
