Can anyone me with this? is equations of lines.

x=16

Step-by-step explanation:

y = 1/2 x -3

Let y =5

5 = 1/2 x -3

Add 3 to each side

5+3 = 1/2 x -3+3

8 = 1/2x

Multiply each side by 2

8*2 = 1/2x*2

16 =x

  16

Step-by-step explanation:

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.
