A support wire is tied diagonally from the middle of a tree to a stake on the ground. The length of the wire is 10 ft and the angle of
elevation from the stake is 55". Approximately how high on the tree is the connection point of the wire?

8.2 ft

.Step-by-step explanation:

Sketch this situation.  Label the 55° angle.  The adjacent side is the distance from the stake to the bottom center of the tree.  The opposite side is the distance from the ground to the connection point of the wire on the tree.  The wire length represents the hypotenuse of this triangle.  We want to find the length of the side opposite the 55° angle.  Thus, we write

sin 55° = (opposite side)/(hypotenuse), or

(hypotenuse)(sin 55°) = (10 ft)(0.819) = 8.2 ft
