Question

the angle of elevation is 60 degree from the top of a 15m high building to the top of a tower and the angle of depression to the bottom of the tower is 30 degree. find the height of the tower and the distance between the tower and the building

Answer 1

Answer:

=60m

Step-by-step explanation:

tan60= x/y=root3

or,

x=yroot3 ------ 1

tan30=15/y= 1/root3

or,

y= 15root3  ----------- 2

Substituting 2 into 1,

x= 15root3 x root3

 =15x3

 =45m

total height of tower= 45+15m

                                 =60m
