Answer:
see below
Step-by-step explanation:
Complements add to 90 degrees
x+40 = 90
x = 90-40
x = 50
Supplements add to 180
y+63 =180
y = 180-63
y = 117
(a)
If the sum of the measures of two angles is 90° they are known as complementary angles.
- Let the value of unknown angle be x.
According to the question
⇨x + 40° = 90°
⇨x = 90° - 40° [Subtract]
⇨x = 50°
Complement angle is 50°

(b)
If the sum of the measures of two angles is 180° they are known as supplementary angles.
- Let the value of unknown angle be x.
According to the question
⇛x + 63° = 180°
⇛x = 180° - 63° [Subtract]
⇛x = 117°
Supplement angle is 117°
