Question

A ladder leaning against a house makes an angle of 60 degrees. The foot of the ladder is 7 feet from the house. How long is the ladder and what would the situtaion look like as a right triangle?

Answer 1

check your 30-60-90 right triangle. Its sides are in the ratio

1:√3:2

You have the short side = 7, so scale it up.

Answer 2

sin60 = 7/L. L = Length of ladder.
L is also the hypotenuse of a right triangle.

Answer 3

actually, cos60 = 7/L

Answer 4

Oops. Henry is right if the angle with the wall is 60
