Question

A 4 meter ladder leans against a house forming a

30° angle with the house. Exactly how far is the
De 7. base of the ladder from the house in meters?

Answer 1

2.meters

Explanation:

Lenght of ladder = 4 m

θ = 30°

To obtain h;

Using Pythagoras rule :

Sinθ = opposite / hypotenus

Hypotenus = 4 ; opposite = h

Sin 30 = h / 4

0.5 = h / 4

h = 0.5 * 4

h = 2 m

Hence, distance between th efoot of ladder and the base of the wall is 2 m
