Answer:

B. 15 and 7

Step-by-step explanation:

Let x and y be the two numbers

x - y = 8

x = y + 8

2x + 3y = 51

2y + 16 + 3y = 51

5y = 35

y = 7

x = 15

Use the value of x to find the measure of angle 1
suter [353]
We know that the angle of a straight line is 180°.

So we know that (5x-5) + (2x+10) = 180
We will then solve for x

5x - 5 + 2x + 10 = 180

7x + 5 = 180

7x = 175

x = 25 (just an explanation of how we get 25)

To get angle 1, we will then plug in x=25 into the first equation to get

5(25)-5 = 125-5 = 120°
