Question 350937
How can I Find the measure of two supplementary angles that measure of the first angle is four times the measure of the second angle?
.
By definition:
the sum of two supplementary angles is 180 degrees
.
Let x= second angle
then
4x = first angle
.
x + 4x = 180
5x = 180
x = 36 degrees (second angle)
.
First angle:
4x = 4(36) = 144 degrees
