Complements add up to 90
Angle = x
its complement = 90 - x
the measure of an angle is 10 less than 4 times the measure of its complement
x = 4(90 - x) - 10
x = 360 - 4x - 10
5x = 350
x = 70

Let x = the angle
Then 90 -x is its complement
So x = 4(90-x)-10
x = 360-4x-10
5x =350
x=70

a = 4(90 - a) - 10
a = 360 - 4a - 10
a = 350 - 4a
5a = 350
a = 70

Î = 4(90 - Î) - 10
Î = 360 - 4Î - 10
5Î = 350
Î = 70

mA = 4*(90-mA) -10
mA = 360 - 4mA -10
mA = 350 - 4mA
5mA = 350
mA = 70º
