Answer:

120°

Step-by-step explanation:

Angle sum Theorem says that the sum of the measures of the interior angles of a triangle is 180 degrees. ... This creates alternate interior angles that are congruent.

Sum of two interior angles equals the opposite exterior angle...

33 + 87 = y

y = 120°

Answer: y = 130 degree

Explanation:

In a triangle the angle sums up to 180 degree.

Find x:

87 + 33 + x = 180
130 + x = 180
x = 50

Find y:

x + y = 180 (straight angle)

But x = 50

=> 50 + y = 180
=> y = 130
