Solve Angles

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle A is 30 degrees, what is the measure of its complementary angle?

Back

60 degrees (90 - 30 = 60).

Front

If angle B is 110 degrees, what is the measure of its supplementary angle?

Back

70 degrees (180 - 110 = 70).

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If two angles are complementary and one angle measures 25 degrees, what is the measure of the other angle?

Back

65 degrees (90 - 25 = 65).

Front

If two angles are supplementary and one angle measures 95 degrees, what is the measure of the other angle?

Back

85 degrees (180 - 95 = 85).

Front

What is the value of x if angle C is 45 degrees and it is complementary to angle D?

Back

45 degrees (90 - 45 = 45).

Front

What is the value of x if angle E is 120 degrees and it is supplementary to angle F?

Back

60 degrees (180 - 120 = 60).

Front

If angle G is 38 degrees, what is the measure of its complementary angle?

Back

52 degrees (90 - 38 = 52).
