Question

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°
(1 point)
Responses

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

x°+77°=180°

Answer 1

The answers to the Check Answers are..
1. m∠1 + 26° = 90°
2. m∠4 + 67° = 180°
3. m∠7 + 45° = 180°
4. m∠C = 75° m∠D = 80°
5. 54°
Hope this helpssssss :)
