UNit 2 Flashcard #2

Front

What are supplementary angles?

Back

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

Front

What is the measure of the missing angle if one angle is 24 degrees?

Back

The missing angle is 156 degrees, since 180 - 24 = 156.

Front

Solve for w: w + 27 = 58

Back

w = 31.

Front

What is the value of x if x + 10 = 76?

Back

x = 66.

Front

Write and solve the equation: Jeremy spent $7 on a sandwich and a drink. If he spent $1.75 on his drink, how much did his sandwich cost?

Back

s + 1.75 = 7 ; s = 5.25.

Front

What are complementary angles?

Back

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

Front

If two angles are supplementary and one angle measures 90 degrees, what is the measure of the other angle?

Back

The other angle measures 90 degrees, since 180 - 90 = 90.

Front

Solve for x: 2x + 10 = 70

Back

x = 30.

Front

What is the formula for finding the measure of an angle in a triangle?

Back

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

Front

If one angle measures 45 degrees, what is the measure of its complementary angle?

Back

The complementary angle measures 45 degrees, since 90 - 45 = 45.
