Answer:
∠4 = 50°
Step-by-step explanation:
∠1 + ∠5 = 100°, but ∠1 = ∠5 ( corresponding angles ), hence
∠1 = ∠5 = 50°
∠4 = ∠1 = 50° ( vertical angles )

Answer:
Step-by-step explanation:
5x - y = -21
y = 5x + 21
Substituting into:
x + y = -3
x + 5x + 21 = -3
6x = -24
x = -4
y = 5(-4) + 21
y = 1
Solution: (-4,1)
