For the triangle shown in the figure below what are each of the following? (Let y = 60.0 m and r = 61.0 m. Assume the triangle is a right triangle.)
Decide which side of the triangle is the hypotenuse and which the remaining two sides, apply the Pythagorean theorem, and then solve for the unknown length.
(a) the length of the unknown side x m
(b) the tangent of θ
(c) the sin of Φ.
