FLASHCARD QUESTION

Front

∠INJ and ∠INM are _ angles.

Back

supplementary angles are two angles whose measures add up to 180°.

2.

FLASHCARD QUESTION

Front

If the measure of an angle is 38°, find the measure of its complement.

Back

The complement of an angle is found by subtracting the angle from 90°. Therefore, the complement of 38° is 90° - 38° = 52°.

3.

FLASHCARD QUESTION

Front

The m∠B is (3x+2)° and m∠C is (x)°. If they are complementary angles, find the value of x.

Back

Complementary angles add up to 90°. So, (3x + 2) + x = 90. Solving gives x = 22°.

4.

FLASHCARD QUESTION

Front

If the measure of an angle is 13°, find the measure of its supplement.

Back

The supplement of an angle is found by subtracting the angle from 180°. Therefore, the supplement of 13° is 180° - 13° = 167°.

5.

FLASHCARD QUESTION

Front

Find the value of x if m∠A = (2x + 10)° and m∠B = (x + 20)° and they are supplementary.

Back

Supplementary angles add up to 180°. So, (2x + 10) + (x + 20) = 180. Solving gives x = 12°.

6.

FLASHCARD QUESTION

Front

Define complementary angles.

Back

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

7.

FLASHCARD QUESTION

Front

Define supplementary angles.

Back

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