Can you help me with this trigonometry question?

Question

If the sides of a triangle are 5,12,13, what is the sine of the smallest angle? I got so far sin 5/13 or 5 over 13

Answer 1

The sides of the triangle are 5, 12, 13.

In the above diagram the smallest angle is Ѳ.

In a triangle ABC, smallest angle is ∠B = SinB = opposite side/ hypotenuse

                                                                                     = 5/13.

Therefore the sine of smallest angle is 5/13.
