Question

Geometry--Supplementary angles are two angles whose measures have the sum of 180 degrees. Angles X and Y are supplementary, and the measure of angle x is 24 degrees greater than the angle Y. Find the measure of angles X and Y Using substitution

Answer 1

X+Y= 180°

X= Y+24°

Y+24°+Y= 180° ---Substitute Y+20° for X.

2Y+24°= 180° ---Simplify.

2Y= 156° ---Subtract 24° from both sides.

Y= 78° ---Divide both sides by 2.

X+Y= 180°

X+78°= 180° ---Substitute 78° for Y.

X= 102° ---Subtract 78° from both sides.

Answer 2

x=y+24

y +(x) =180

y+ (y+24) =180

2y +24=180

2y =156

y =78º

x=78+24 =102º
