If the measure of an angle is 78 less than the measure of its compliment, what is the measure of the angle?
aliina [53]
Complementary angles add up to 90'
So let X= angle 1
         Y=angle 2
So x+y=90
let x=y-78
so(y-78)+y=90
y-78+y=90
2y-78=90
2y=90+78
2y=168
y=168/2
y=84
x=y-78
so x=84-78
x=6
And 6+84=90
So the measure of the angle is 6 degrees.
Hope i helped!
