Answer:
x = 83°
y = 83°
Step-by-step explanation:
Angles in a triangle add up to 180°, so:
Equation: 31 + 66 + x = 180
Combine like terms: 97 + x = 180
Subtract 97 from both sides: x = 83°
They are vertical angles (x = y), y will also be 83°!
Step-by-step explanation:
x+31°+66°=180°
x=180°-31°-66°
x=83°
and x°=y° due to both are vertically opposite angle.
y°=83°.
hope this helps you.
