Answer:

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

Answer: 55 degrees

Answer:

Slope = -5/8

Step-by-step explanation:

Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).

We are going to use the formula for finding the slope of a line now.

y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8

Slope = -5/8
