Answer:
the supplementary angle to 313 would be 49.
Step-by-step explanation:
the supplement of an angle is when tow angles add up to equal 180 degrees. therefore, if you subtract 131 from 180, you would get the answer of 49 degrees.
49° is the supplementary angle of 131°.
Two angles x° and y° are called supplementary angles if x°+y°=180°.
Let x° be the supplementary angle of 131° then,
x°+131°=180°
then,
supplementary angle x°=(180-131)°=49°
Thus the supplementary angle of 131° is 49°.
