Question 650507: angle a and angle b are supplementary. Twice the measure of angle a is one-half the measure of angle b. find the angle of measure b Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! angle a and angle b are supplementary. Twice the measure of angle a is one-half the measure of angle b. find the angle of measure b
**
a+b=180º
a=180-b
..
2a=b/2
2(180-b)=b/2
360 -2b=b/2
720-4b=b
5b=720
b=144
angle of measure b=144º
