Question

Angle 1 and Angle 2 are supplementary. If m∠1=27° , what is m∠2 ?

Answer 1

Suppose m∠1 = x degree

m∠2 = 17 x degree

As angle 1 & 2 are supplementary angles so

m∠1 +m∠2 =180 degree...... eq 1
Substituting the values of angle 1 & 2 in eq 1, we get

x +17x =180
18x=180
x= 180/18 =10 degree
17 x= 170 degree
m∠1 = 10 degree m∠2 = 170 degree.
