Answer:

y =65

Explanation:

We will call the unknown angle in the triangle x

Angle x plus 130 form a straight line

x+130 = 180

Subtract 130 from each side

x+130-130 = 180-130

x = 50


The three angles in the triangle add together to make 180 degrees

x+y+y = 180

We know angle x = 50

50 + 2y = 180

Subtract 50 from each side

50+2y-50 = 180-50

2y = 130

Divide each side by 2

2y/2 = 130/2

y = 65
