Its A
because sin A is CB/AB
and cos A is AC/AB
<span>3(5x + 4) - 20 - 13x = -4
first use the distributive property with </span><span>3(5x + 4)
15x+12-20-13x=-4
combine like terms
2x-8=-4
add 8 to both sides
2x=4
divide both sides by 2
x=2</span>

So it is very Clear that Option 2 is a function and the other are not function. I have marked Which are function and which are not.

2002— 64/100 x
now we need to get x from 64/100 x
