Answer:
y=-2x+10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(8-(-10))/(1-10)
m=(8+10)/-9
m=18/-9
m=-2
------------------
y-y1=m(x-x1)
y-(-10)=-2(x-10)
y+10=-2x+20
y=-2x+20-10
y=-2x+10
92 degrees
Triangle= 180 degrees
180-60-28= 92
:)
Area = 256*3.14=804feet^2
47.5 mph- because 30+65 equals 95 and 95 divided by 2 is 47.5
