Angle of Elevation of Nursery Plants

Question

A nursery plants a new tree and attaches a guy wire to help support the tree while its roots take hold. An eight foot wire is attached to the tree and to a stake in the ground. From the stake in the ground the angle of elevation of the connection with the tree is 42º. Find to the nearest tenth of a foot, the height of the connection point on the tree.

Answer 1

 The "angle of elevation" is from the ground up.

• It is assumed that the tree is vertical, making it perpendicular with the ground.

• This problem deals with "opposite" and "hypotenuse" making it a sine problem.

•
