Answer:
y = 68 because of the equation 2y + (y - 24 ) = 180, Angle Sum postulate
Step-by-step explanation:
Because line PQ is a straight line, we see it measures 180 degrees.
So that means 2y + (y - 24) = 180 degrees.
Those two angles add up to 180 degrees.
so we can solve this equation for y now.
2y + (y - 24) = 180
3y - 24 = 180
3y = 180 + 24
3y = 204
y = 204/3 = 68
That is how y = 68.
Then the 2*y = 2*68 = 136 degrees.
and the other angle y - 24 = 68 - 24 = 44 degrees.
