(3x + 8) degrees

(1 point)

A. 10

B.15

C.20

D. 25

Answer 1

To find the value of x, we can set the two expressions equal to each other and solve for x.

(5x + 12) degrees = (3x + 8) degrees

First, let's remove the degrees symbol as it does not affect the equation:

5x + 12 = 3x + 8

Next, we want to isolate the x term on one side of the equation. Let's subtract 3x from both sides:

5x - 3x + 12 = 3x - 3x + 8

2x + 12 = 8

Now, let's subtract 12 from both sides:

2x + 12 - 12 = 8 - 12

2x = -4

Finally, divide both sides by 2 to solve for x:

(2x)/2 = (-4)/2

x = -2

Therefore, the value of x is -2. None of the options A, B, C, D are correct.
