x = 30°

Find the value of x. <br><br><br>A.20 <br><br>B.25 <br><br>C.18.75 <br><br>D.22.5
miss Akunina [59]

The two equations are vertical angle, which would be equal to each other.

Set the equations to equal and solve for x:

5x -10 = 3x +40

Subtract 3x from both sides:

2x -10 = 40

Add 10 to both sides:

2x = 50

Divide both sides by 2:

x = 50 / 2

x = 25

The answer is B. 25
