Answer:

y = 25°

Explanation:

115° and x are a linear pair and sum to 180° , so

x + 115° = 180° ( subtract 115° from both sides )

x = 65°

the sum of the 3 angles in the triangle = 180° , then

x + x + 2y = 180°

65° + 65° + 2y = 180°

130° + 2y = 180° ( subtract 150° from both sides )

2y = 50° ( divide both sides by 2 )

y = 25°
