Question 965345: If angle a and angle b are supplementary angles and angle A is four times as large as angle b than what would there measurements be> Answer by rm29924(97) (Show Source):
You can put this solution on YOUR website! supplementary angles add up to 180 degrees
so we know a + b = 180
a is four times as large as b
so a = 4b
substitute 4b for a into a + b = 180
4b + b =180
combine like terms
5b = 180
divide both sides by 5 to get the variable b by itself
b = 36
plug 36 back into the original equation to figure out what a is
a + 36 = 180
subtract 36 from both sides
a = 144
answer angle a is 144 degrees and angle b is 36 degrees
