Im confused plz help. I will mark brainliest plus points 20 x 11/15 in steps

44/3

Step-by-step explanation:

20 is also equal to 20/1

so then we have

20/1*11/15

we multiply the numerators (top) together and keep it on top, and mutiply the denominators (bottom) together and keep it on the bottom

so

20*11/1*15

this equals

220/15

we can divide both the top and bottom by 5 to simplify

44/3

this also equals

14 2/3

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.
