Which, if any, of the following is incorrect a. sin A = 29/21
b. cos A = 20/29
c. tan A = 21/20
d. all of the above are correct

(picture included) (please help, i need to pass this to pass my class)

goog may have it for you

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

hey there : ) your answer would be a.
