Question

A mirror is placed on the ground so that the top of the Burj Khalifa Tower can be seen by you in the mirror. You are facing the tower and looking into the mirror. Take your height as 1.80 m. You are 6 m away from the mirror and observe the top of the tower when the mirror is 2.76 km from the tower, (Draw the two similar triangles) find the height of Burj Khalifa Tower.​

Answer 1

828 m

Explanation:

x1 = 6 m

h1 = 1.80 m

x2 = 2.76 km = 2760 m

h2 = ?

h1 : h2 = x1 : x2

1.80 : h2 = 6 : 2760

6 × h2 = 2760 × 1.80

h2 = 828 m
