Hey!

Let's write the problem.
$2x-4-5x=2$
Add like terms...
$-3x-4=2$
Add $4$ to both sides.
$-3x-4+4=2+4$
$-3x=6$
Divide both sides by $-3$ .
$\frac{-3x}{-3}=\frac{6}{-3}$

Our final answer would be,
$x=-2$

Thanks!

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
