Question

A rectangular wall is 32 m high and 13 m long. If its shadow is a parallelogram whose height is 2 times the height of the wall, find the area of the shadow.

Answer 1

Answer:

In △ABC and △DEF

∠A=∠D=90

∘

Since the tower and the stick cast their respective shadows at the same time on the ground,

So, ∠C=∠F

∴△ABC∼△DEF ....(by AA similarity)

Answer 2

Answer:

In ∆ABC and ∆ DEF

Step-by-step explanation:

Angle A = angle D

Science the tower and the stick respective shadow at the same on the ground

So angle C = angle D

∆ABC - ∆DEF

DEAB = DFAC

→ x+12 = 40-8

→ x= 60
