Can someone please help with this question? (See photo) :)

sin(x) = 6/10. cos(y) = 6/10. The relationship is that sin(x)/cos(y) = 1 and or cos(y)/sin(x) = 1

Step-by-step explanation: First we solve for the hypotenuse using the pythagorean theorem 8^2 + 6^2 = x^2 = 100 then we do sqrt(100) = 10. So the hypotenuse is 10. The value of sin(x) is the opposite/hypotenuse. So this makes it 6/10. The cos(y) is going to be the adjacent/hypotenuse. The adjacent side is 6. So cos(y) is also 6/10. Their relationship is that if you take sin(y)/cos(x) it = 1. 6/10 / 6/10 = 1.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
