One leg of a right triangle is twice the length of the other leg What is the cosine of the angle between the longer leg and the hypotenuse?

Shorter leg = 1

Longer leg = 2

Hypotenuse = sqrt(5)

Cosine of angle between the longer leg and the hypotenuse = 2 / sqrt(5) = 0.89443 (rounded)

The angle is 26.565 degrees (rounded)
