ladder from the wall is 50 m, find the height at which the window is placed from
the ground
​

Answer 1

Answer:

120 m

Step-by-step explanation:

when the ladder is used it forms right angled triangle, by Pythagoras theorem, leg (b)

b= ✓(c² - a²)

b= ✓{(130m)²-(50m)²}

b=✓{16900m²- 2500m²}

b=✓{14400m²}

b= 120 m
