In triangle abc, what is the value of sin c?

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

put all the value mentioned above

Thus the correct option is second.

Hence proved

f is the midpoint of

i think it would be 42cm
