Question

Angle A and angle B are vertical angles with M angle A= x and M angle B equals 3X -60. What is M angle A

Answer 1

Answer:

Vertical angles are always equal.

So you can set the equation up like this:

5x + 10 = 7x - 12

Subtract 5x from both sides. Then Add 12 to both sides.

22 = 2x

Divide both sides by 2.

11 = x

 

Answer 2

Answer:

m angle A = x = 30 degrees

Step-by-step explanation:

Vertical angles are equal.

So 3x - 60 = x

2x = 60

x = 30
