Find the measure of angle y. round your answer to the nearest hundredth ( type the numerical answer only)

11.54

Step-by-step explanation:

cos(x) = 4/20

x = cos-1 (4/20) = 78.46°

y = 90° - 78.46°

y = 11.54°

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
