Detailed Solution

tan θ = 0.75

, then sin θ =

35

.
Given that,

tan θ = 0.75

.
Tangent is a ratio of the side opposite to the angle

θ

by side adjacent to the angle

θ

. If k is any positive integer,

tan θ = 75 k 100 k ⇒ O p p o s i t e side Adjacent side = 3 k 4 k

Form a triangle with respect to

θ

with opposite side as BC and adjacent side (AB).

By applying Pythagoras theorem, we get,

A C 2 = B C 2 + A B 2 ⇒ A C 2 = 9 k 2 + 16 k 2 ⇒ A C 2 = 25 k 2 ⇒ A C = 5 k

sin θ = Opposite side H y p o t e n u s e ⇒ sin θ = B C A C ⇒ sin θ = 3 k 5 k ⇒ sin θ = 35

So, the value of

sin θ

35

.
Hence, the correct answer is

35
