Step-by-step explanation:

y-y1=m(x-x1). m=8/3 and x1=5 and y1=3

y-3=8/3(x-5)

3*(y-3)=8(x-5)

3y-9=8x-40

8x-3y=40-9

8x-3y=31

so is the third

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
