The measure of an angle is 10.3°. what is the measure of a supplementary angle?

If two angles are supplementary, then they will equal 180 degrees. So, what you do is subtract 10.3 from 180, which gives you 169.7 degrees. Therefore, the measure of the supplementary angle is 169.7 degrees.

Hope this helps.

Iwish i knew the answer but i don’t but someone will come and us
