In triangle abc, sin a = 24 25 . which other expression has a value of 24 25 ? a) sin b b) cos a c) cos b d) tan a

Option C). cosB

Step-by-step explanation:

In the picture attached by sin rule sin A = 24/25 means

sin A = BC/AB = 24/25

Now for the same value or same ratio will be of cosine of angle B for which height of the triangle will become base of the triangle.

cos B = BC/AB = 24/25

Therefore option C) cos B is the answer.

1/3 + 1/5 = 8/15.
