Question

The measure of an angle is 34 degrees what is the measure of its supplement

Answer 1

supplementary angles = 180 degrees

 so 180 - 34 = 146

 the other angle is 146 degrees

Answer 2

Hey there!

We would have to remember that (supplement) angles are always $180$°. So, sense this would be the case, if that  measure of an angle is 34 degrees, we would then obviously subtract it then.

$\left[\begin{array}{ccc}\boxed{\boxed{180 - 34}}\end{array}\right] = \left[\begin{array}{ccc}\boxed{\boxed{146 \ would \ be \ the \ answer}}\end{array}\right]$

Hope this helps you dear!
