Question

In triangle ABC, what is the value of sin C?

Answer 1

Given

In ΔABC

Find out the value of sin C.

To proof

As shown in diagram

∠BAC = 90°

AB = c

BC = a

CA = b

in Δ ABC

AB is perpendicular

AC is base

BC is hypotenuse

Now by trignometric function

`sinC =(Perpendicular)/(Hypotenuse)`

`sinC = (AB)/(BC)`

put all the value mentioned above

`sinC =(c)/(a)`

Thus the correct option is second.

Hence proved
