An angle measures seventeen more than three times a number. its supplement is three more than seven times the number. what is the measure of each angle?

If the angles are supplementary angles, that means that they add up to be 180˚.

Angle A is 3x+17 (17 more than 3 times a number) and Angle B is 7x+3 (3 more than 7 times the number).

Both of these added together is equal to 180, so you get: 3x+17+7x+3=180

Combine like terms and get: 10x+20=180

Subtract 20 from both sides: 10x=160

Divide both sides by 10: x=16

Now you have your number.

To find the angles, plug the number back into the statements.

Angle A: 3(16)+17=65˚

Angle B: 7(16)+3=115˚

Check to make sure they add up to equal 180: 65+115=180 √

And you're done!
