• 1.

### Complementary angles are angles that add up to 180.

• A.

True

• B.

False

B. False
Explanation
Complementary angles are angles that add up to 90 degrees, not 180 degrees.

• 2.

### These two angles are complementary.  What is the measure of angle x?

• A.

30 degrees

• B.

28 degrees

• C.

26 degrees

• D.

118 degrees

B. 28 degrees
Explanation
The two angles are complementary, which means that they add up to 90 degrees. Since angle x is one of the angles, its measure must be such that when added to the other angle, the sum is 90 degrees. The only option that satisfies this condition is 28 degrees, as 28 + 62 = 90. Therefore, the measure of angle x is 28 degrees.

142 degrees

D. 142 degrees
Explanation
The measure of angle x is 142 degrees because it is the only option that is not too small or too large. It is also the closest option to a right angle, which is 90 degrees.
