Answer 2

Step-by-step explanation:

Let PQ is a wall of height h. Let QR is ladder and QR = 1.5 m.

Since ladder makes an angle 60° with the ground i.e., ∠PRQ = 60°.

From right angled ΔPQR tan 60° = PQ/QR ⇒ √3 = h/1.5 h = 1.5 × √3 = 1.5 × 1.732 [∵ √3 = 1.732] = 2.598 m = 2.60 m

Hence, height of wall = 2.60
