It two angles are equal and supplementary, the angles are

Select one:

a. right angles

b. obtuse angles

c. acute angles

The answer would be A, right angles.

Step-by-step explanation:

This is because supplementary angles add up to 180 degrees. Since these two angles are equal to each other and they have to equal 180, you can make an equation out of this. 2x = 180. If you divide both sides by 2, you would x=90. Only right angles have an angle of 90 degrees.
