Question

Supplementary Angles Practice
angles j and k are supplementary angles

Answer 1

If angles J and K are supplementary angles, it means that the sum of their measures is 180 degrees.

So, if angle J measures x degrees, angle K measures 180 - x degrees.

For example, if angle J measures 60 degrees, angle K measures 180 - 60 = 120 degrees.

Some practice problems could be:

1. Angle J measures 30 degrees. What is the measure of angle K?
Answer: Angle K measures 180 - 30 = 150 degrees.

2. Angle K measures 75 degrees. What is the measure of angle J?
Answer: Angle J measures 180 - 75 = 105 degrees.

3. Angle J measures 90 degrees. What is the measure of angle K?
Answer: Angle K measures 180 - 90 = 90 degrees.

Remember, the sum of the measures of supplementary angles is always 180 degrees.
