A hunter 1.6 m tall, views a bird on top of a tree at an angle of 45°. if the distance between the hunter and the tree is 10.4 m, find the height of the tree.

A.

9.0 m

B.

12. 0 m

C.

8.8 m

D.

10.4 m

Correct Answer: 12. 0 m

Explanation

tan 45 = x/10.4 = 10.4m height of the tree is equal to 1.6m + 10.4m = 12m

tan 45 = x/10.4 = 10.4m height of the tree is equal to 1.6m + 10.4m = 12m
