Answer 2

Answer:

Using the property -

Exterior angle = Sum of interior opposite angles

Exterior angle = 130°

One of the interior opposite angle = 120°

Other interior opposite angle = x

130° = 120° + x

x = 130° - 120°

x = 10°

Now , Using Angle Sum Property -

Sum of all the three angles of triangle = 180°

One Angle = 120°

Second Angle = 10°

Third Angle = y

120° + 10° + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Hence , the value of x is 10° and y is 50°
