Question

A ladder 17 m long is placed at a distance of 15 m away from the wall to reach
a window. Find the height of the window. If the ladder is kept at a distance of
8 m away from the wall, it reaches the roof. What is the height of the roof
above the ground?
11
17 m​

Answer 1

Answer:

height of window=8 metre

height of roof= 15 metre

Step-by-step explanation:

(base)²+ (height)² = (hypotenuse)²

(15)²m+ h²= (17)²m

h²= 289m - 225m

h²= 64m

h= (√64)m

h= 8m

Therefore, height of window =8m

second question

(base)²+ (height)² = (hypotenuse)²

(8)²m+ (h)²= (17)²m

h²= 289m - 64m

h² = 225m

h=(√225)m

h = 15m

Therefore height of roof = 15m

Hope it helps
