Find the slope of the line that passes through (72, 60) and (73, -5).

-65

Step-by-step explanation:

We can use the slope formula

m= (y2-y1)/(x2-x1)

   = (-5-60)/(73-72)

   = -65/1

  = -65

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
