Question

Two chimneys 18 m and 13 m high stand upright on a ground. If their feet are 12 m apart, then find the distance between their tops. (Hint : Find AD) please answer me fast. Answer is coming 18.5 m.
​

Answer 1

Answer:

AD = 13

Step-by-step explanation:

According to the question, the chimneys are parallel. So, BC = ED = 12m and AE = 18m - 13m = 5m .

Now, ∆AED a right angled triangle.

So, AD is the hypotenuse ( largest side of the triangle).

AD^2 = AE^2 + ED^2

or,AD^2 = 5^2 + 12^2

or,AD^2 = 169

or, AD = √169

or,AD = 13
