Question

If an angle is supplementary and one measures 70° what is the measure if the other angle?

Answer 1

Supplementary is 180 degree, if one measure 70, then use 180-70=110 is the other angle

Answer 2

The other angle is 110

Explanation:

Supplementary angles add to 180

Let x be the other angle

70+x = 180

Subtract 70 from each side

70+x-70 = 180-70

x = 110
