Two angles, ∠1
and ∠2
, in a diagram are supplementary. If m∠1=77° , what equation can you write to solve for m∠2 ? Let m∠2=x°

x°+77°=180°
x plus 77 degrees equals 180 degrees
x°=77°
x equals 77 degrees
x°=90°−77°
x equals 90 degrees minus 77 degrees
x°+77°=90°
x plus 77 degrees equals 90 degrees
supplementary
My apologies for the incorrect response. Since the angles are supplementary, their sum must be 180 degrees. Therefore, the correct equation to solve for m∠2 is:
m∠2 + 77° = 180°
