let the angle be x
the equation
180-x=4(90-x)+30
180-x=360-4x+30
3x=210
x=70
xheck complement=20
4 times the complement=80
180-110=70

I saw this one yesterday! Or, one almost exactly like it. The angle= 50 Check: 50+40=90 40*4=160 160+50=210 210-30=180
rfamilymember: 180-x=4(90-x)-(MINUS)30

What are you talking about?
Supplementary = 180 degrees
Complementary = 90 degrees
It should two angles that are either supplementary or complementary.

(180 - x) = 4(90 - x) - 30
180 - x = 360 - 4x - 30
180 - x = 330 - 4x
3x = 150
x = 50
ANS : 50°
