Question

Two angles make a vertical pair: m<1 = (3x + 15) ° and m/3 = (x + 45)°. What is the measure of each angle?

Since the two angles are a vertical pair, they are equal in measure. Therefore, we can set their expressions equal to each other:

3x + 15 = x + 45

Subtract x from both sides:

2x + 15 = 45

Subtract 15 from both sides:

2x = 30

Divide both sides by 2:

x = 15

Now, we can find the measure of each angle by substituting x back into the expressions:

m<1 = 3(15) + 15 = 45 + 15 = 60°
m<3 = 15 + 45 = 60°

So, each angle measures 60°.
