Angle sum theorem - what would y equal to? will give brainliest!

55 degrees

Step-by-step explanation:

The sum of the measures of the angles of triangle is 180 degrees.

That allows you to find the value of x.

x + 25 + 30 = 180

x + 55 = 180

x = 125

To find y, use the fact that angles x and y are supplementary. The measures of two supplementary angles add to 180 deg.

y + x = 180

y + 125 = 180

y = 55

55 degrees

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0
