Given \tan a = \frac{7}{{24}}, find the cos b

We are given

we know that

so, we get

opposite =7

adjacent=24

now, we can find hypotenuse

now, we can draw triangle and then switch vertices accordingly

we can find cos(B) using second triangle

In second triangle:

adjacent=7

hypotenuse =25

so, we get
