Answer:
4°
Step-by-step explanation:
let the angle be x, then 180 - x is it's supplement and 90 - x it's complement.
thus
180 - x = 2(90 - x) + 4 ( supplement = 4 more than twice complement )
180 - x = 180 - 2x + 4
180 - x = 184 - 2x ( add 2x to both sides )
180 + x = 184 ( subtract 180 from both sides )
x = 4
Thus angle = 4°
As a check
supplement = 180 - 4 = 176
and 2(90 - 4 ) + 4 = (2 × 86 ) + 4 = 172 + 4 = 176 ← checks
