Given \tan A = \frac{7}{{24}}, find the cos B
Natali5045456 [20]

We are given

tan(A)=\frac{7}{24}

we know that

tan(A)=\frac{opposite}{adjacent}

so, we get

opposite =7

adjacent=24

now, we can find hypotenuse

hypotenuse=\sqrt{7^2+24^2}

hypotenuse=25

now, we can draw triangle and then switch vertices accordingly

we can find cos(B) using second triangle

cos(B)=\frac{adjacent}{hypotenuse}

In second triangle:

adjacent=7

hypotenuse =25

so, we get

cos(B)=\frac{7}{25}................Answer
