Step-by-step explanation:
Right angle = 90°
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90, x = 29.
Supplementary angles = Angles that add up to 180°.
x + (x + 104) = 180
2x = 76, x = 38.
Answer:
117 degrees
Step-by-step explanation:
theres no picture and not alot of context so i just subtracted 180 and 63
