Question

Mrs. Griffin bought a new tree and attached a 15-foot wire set at an angle of elevation of 25​°​ to support her tree from the top. Find the height of the tree.

Answer 1

The tree, wire and the ground form a right angled triangle. since the angle of elevation is 25 degrees, this is the angle between the ground and the wire.

Wire is the hypotenuse, tree is the opposite (vertical) and ground is the base

Since tree is the vertical, 15•sin25° = 6.34 feet
