Question

Find the value of the trigonometric function in fraction form for triangle ABC.

AB=25,
BC=7
CA=24
What is the cosine of ∠B?
​

Answer 1

Answer:

$\cos \: B = \frac{base}{hypotenuse } \\ = > \frac{7}{25}$

Answer 2

We know that

cos B = base / hypotenuse

= BC / AB

= 7 / 25

Answer = 7/25
