Answer:

x = 125°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for x, that is

x = 180° - (30 + 25)° = 180° - 55° = 125°

y=25+30, so y=55
x=180-55, so x=125
the outside angle is equal to the sum of the two other angles (the ones it is not adjacent to), so y would be 55, and since y and x are supplementary, x would be 125.
