Knowing that sin 20 = a what is a
5
A, 2.5
B, 10
C. 8.66
D. 5

step-by-step explanation: yes

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
