Question

21) A ladder is 17m long. It reaches a window at a height h above the ground. If the
foot of ladder is at the distance 8m from the wall. Find the height of the
window.

Answer 1

Answer:15m

Step-by-step explanation:

here,ladder=hypotenuse=17m

distance from the wall =base=8m

Applying Pythagoras therom

Hypoteneuse²=perpendicular² +base²

or 17²= h²+8²

or289=h²+64

or h=✓289-64

or h=✓225

or h=15m

therefore,the height of the window is 15m from the ground
