Answer 1

Answer:

y= 85 degrees

Step-by-step explanation:

We know angle BCD is 50 because we have a straight line, and the sum of the angles in a line is 180. 180-130=50

Using that same logic, we now know ADC, because 180-55=125.

The sum of the angles in a quadrilateral is 360. Since we know 3 of the angles in quadrilateral ABCD, we can figure out angle ABC.  360-125-50-90=95. So we know angle ABC is 95.

y is 180-95=85

y=85
