The measure of the right angle is 90 degrees. add 25 to 90 to get 115. 180-115= 65 so your answer is 65
Just do 7 x 5 = 35.............
The rate of change is also called the slope
the formula foe the rate of change is (y2-y1) / (x2-x1)
x1 = -3
x2 = 6
y1 = 14
y2 = -1
rate of change = (-1 - 14) / (6- (-3)
= -15 / 9
= -5/3
