Question

Using the information in the diagram, what is the height of the tree to the nearest foot?

45 ft
54 ft
60 ft
135 ft

Answer 1

Answer:

60 ft

Step-by-step explanation:

a = 90

b = 108ft

the base angle can be found by using sin(x) = 120/108x2

=> x = 33.7 degrees

To find height, use tan(33.7) = Opp/ Adjacent = x / 90

=> x = 60.02 or 60 ft
