Front

If two angles are complementary and one angle measures 35°, what is the measure of the other angle?

Back

55°.

Front

How do you find the value of x in complementary angles?

Back

Set up the equation: angle1 + angle2 = 90° and solve for x.

Front

How do you find the value of x in supplementary angles?

Back

Set up the equation: angle1 + angle2 = 180° and solve for x.

Front

What is the relationship between adjacent angles and straight angles?

Back

Adjacent angles can combine to form a straight angle.

Front

What is the formula for finding the measure of an angle if given its complement?

Back

Complement = 90° - angle.
