Answer:
x = 35° , y = 85°
Explanation:
(2x+25) = (3x-10) // Reason: Vertical Angles are Congruent (have equal values)
Now we solve this...
2x+25 = 3x-10
25+10 = 3x-2x // Bring alike terms to one side
35 = 3x-2x
35 = x, so x = 35 °

Now, to find y...
-----
We know that x is 35°, and we know that the two top angles in the picture are supplementary (meaning that they add up to 180°)
(2x+25) = 70 + 25 = 95
So 180° - 95° = y
y = 85°
