7. If A is congruent to B, than they have the same angle measure.
The supplement of B measures 22 degrees. Two angles that are supplementary to each other means that their sums add up to 180 degrees. To find B and A, subtract 22 from 180:
180-22=158 degrees. m
8. P is a right angle, which means it is 90 degrees. Remembering about supplementary angles, that means angle Q is also 90 degrees, as 90+90=180.
9. If
10. If an angle is obtuse (greater than 90 degrees), then it’s supplement must be an acute angle. This is because an obtuse angle is greater than 90 degrees, and an acute angle is less than 90 degrees. 180 minus something greater than 90 degrees is going to give you an angle less than 90 degrees, therefore being an acute angle.
