Answer:subtraction property
Step-by-step explanation:
Two a negative and a negative makes a positive so it would be x+6=18 so u do the opposite on both sides so it would be subtraction
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.
