Answer:

117 degrees

Step-by-step explanation:

Two vertical angles will always equal each other.

So, set up an equation where angle A and angle B equal each other to solve for x:

5x - 3 = 4x + 21

5x = 4x + 24

x = 24

Plug in 24 for x in the expression represent angle A:

5(24) - 3

rusak2 [61]

Answer:

$8.8 per hour

Step-by-step explanation:

Well, the equation is simple.

Time (hours) * Money (per hour) = Total

We know the time he worked for and the total amount he earned, so just replace in this equation and find the unknown number

12.5 * money = 110

To find the money he earns per hour we should just simply divide the total amount he earned by the hours he spent working

money = 110/12.5

money = 8.8$

You can also check it out to make sure it's correct.

If he earns 8.8$ per hour and worked for 12.5 hours how much he'll earn? Let's find out

8.8 * 12.5 =?

8.8 * 12.5 = 110, the same total amount so our solution must be correct.
