So basically x is equal to 7. That means that you need to plug 7 in for x. It should look like this: 5(7) +2. You can then plug that into your calculator in order to get 37!

I really hope that helped you understand!!

You have to substitute the x so since x=7 you have to do 5x7 which is 35 then you add the 2 making 37. Just tell me if you have any questions

Answer:

∠ A ≈ 44.42°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos A = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{5}{7}$ , then

∠ A = $cos^{-1}$ ( $\frac{5}{7}$ ) ≈ 44.42° ( to the nearest hundredth )
