Question

If two angles are supplementary and one angle measures 47°, what is the measure of the other angle? 43° 133° 53° 47°

Answer 1

47 degrees

Explanation:

Exterior angles have to add up to 360 degrees

360-100-127=133

133+47=180

47

yay

Answer 2

x = 133

Explanation:

Supplementary angles add to 180 degrees. Call the unknown angle x

47 +x = 180

Subtract 47 from each side

47-47+x =180-47

x = 133
