- 7 + 4m + 10 = 15 - 2m
4m + 2m = 15 + 7 - 10
6m = 12
m = 12 : 6
m = 2
---------------------------------------
- 7 + 4 * 2 + 10 = 15 - 2 * 2
- 7 + 8 + 10 = 15 - 4
11 = 11

4m+2m=7-10+15
6m=12
m=12:6
m=2

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!
