The value of x and y are 25⁰ and 26.7⁰.
What is alternate angles?
Alternate angles are a pair of angles formed by a transversal intersecting two lines. They are on opposite sides of the transversal and are equal in measure.
From the figure
4x = 100 (alternate angles)
x = 100/4
x = 25⁰
3y + 100 = 180(linear angles)
3y = 180 - 100
3y = 80
y = 80/3
= 26.7⁰
Therefore, the value of x and y are 25⁰ and 26.7⁰.
