Answer:
x = 45, y = 85
Explanation:
In this figure we can see a Z-angle, which tells us that x = 45
In a triangle, the sum of the angles is 180 degrees,
so the unknown angle in the triangle is 180 - 45 - 85 = 50
For a straight line, the total angle is 180 degrees,
, so y + x + unknown angle of triangle = 180
since x = 45, and unknown angle of triangle = 50,
y = 180 - 45 - 50 = 85
This can also be seen when you realise that the two parallel lines give an F-angle, which tells us that Y = 85
