Answer:
4 deg is the answer
Step-by-step explanation:
know these things
supplementary angles add up to 180 deg and
complementary angles add up to 90 deg.
now, let the unknown angle be x
supplementary angle of x = S = 180 - x
and
complementary angle of x = C = 90 - x
from the given statement
[tex]s \: = 2 \times c \: + 4 \\ (180 - x) = (2 \times (90 - x)) + 4 \\ 180 - x = 180 - 2x + 4 \\ - x + 2x = 180 + 4 - 180 \\ x = 4[/tex]
