A ladder 16m long leans against an electric pole. If the ladder makes an angle of 65o with the ground, how far up the electric pole does its top reach
A
6.8m
B
14.5m
C
17.7m
D
34.3m
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Sin 65o = \(\frac{x}{16}\)
x = 16x sin 65
= 16 x 0.9063
x = 14.5m
