Answer:
x = 75°
y = 35°
Step-by-step explanation:
We know that the interior angles of a triangle add up to 180°.
70° + x + y = 180°
x + y = 110°.
x = 110° - y - (1)
We also know that the interior and exterior angle of a triangle add up to 180°.
x + 3y = 180°
Plugging in the value of x from (1),
110° - y + 3y = 180°
110° + 2y = 180°
2y = 70°
y = 35°
x + y = 110°
x + 35° = 110
x = 75°
