Asked by Skylar

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?
Answered by Steve
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.
Answered by Henry
sin60 = 7/L. L = Length of ladder.
L is also the hypotenuse of a right triangle.

Answered by Steve
actually, cos60 = 7/L
Answered by Steve
Oops. Henry is right if the angle with the wall is 60
