Question

A 10 meter long ladder leans against a wall in such a way that foot of the ladder
is 5 meter. Away from the wall. Then find the angle made by the ladder with
ground and wall.
(a) 30
(b) 45
(C) 60
(d) 90
​

Answer 1

Answer:

Ladder length = 10 m

Distance between foot of ladder and wall = 5 m

So, in trigonometry form

$\frac{b}{h} = \frac{5}{10} = cos \alpha = 0.5$

$\alpha = 60$
