Answer:
8m
Step-by-step explanation
The set up is a right triangle
Given
The distance of pole from the base = 6m
Length of the pole = 10m
Required
Height of the telephone pole h
Using the pythagoras theorem;
hyp^2 = opp^2 + adj*2
10^2 = 6^2 + h^2
h^2 = 10^2 - 6^2
h^2 = 100 - 36
h^2 = 64
h = √64
h = 8m
Hence the height of the telephone pole is 8m
