Two angles are supplementary one of them is 24 more than twice the other how large is the other angle

Advocard [28]

Answer:

Angle 1: 52 degrees

Angle 2: 128 degrees

Step-by-step explanation:

Angle 1 = x

Angle 2 = 2x + 24

Supplementary angles are two angles that add up to 180 degrees.

x + 2x + 24 = 180

3x + 24 = 180

3x = 180 -24

3x = 156

x = 52

Check:

Angle 1: x = 52

Angle 2: 2x + 24

2(52) + 24

104 + 24 = 128

128 + 52 = 180

What is the measure of angle B in degrees

Hunter-Best [27]

Angle C and the 112 degree angle are supplementary, so angle C measures 180-112=68 degrees.

This means that by the exterior angle theorem, $m\angle B=51^{\circ}+68^{\circ}=\boxed{119^{\circ}}$
