Question

two poles 30m and 25m high stand upright in a playground. if the poles are 20m apart, find the distance between their topmost points​

Answer 1

Answer:

Here is your answer -----

As seen in the above diagram, the distance between top points = AB

∆ABC = Right-angled Triangle right angled at C.

By the Pythagoras Theorem,

=> (AB)^2 = (AC)^2 + (BC)^2

=> x^2 = (15)^2 + (20)^2

=> x^2 = 225 + 400

=> x^2 = 625

=> x = √(625)

=> x = √(5 × 5 × 5 × 5)

=> x = 5 × 5

=> x = 25

AB = x = 25 m

Hence the distance between their top points is 25 meters.
