Question

An angle measures 142° less than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

Answer:

• 19° and 161°

Step-by-step explanation:

Supplementary angles add up to 180°

• x + (x + 142°) = 180°
• 2x = 180° - 142°
• 2x = 38°
• x = 19°

The other angle

• x + 142° = 19°  + 142° = 161°
