Answer:
It 5 would not be x
Step-by-step explanation:
If 5 was x, then it would be equivalent, because 5+3 = 8. I hope this helped.
Ok, so we know that RST is equal to 6x+12
And RST is also equal to 78 + 3x-12
so we set them equal to each other
6x + 12 = 3x - 12 + 78
And simplify
3x = 54
x = 18
Finally, we solve for the angle with 18 for x
6(18) + 12
108 + 12
120

632=.60 x (it is important to convert the percentage to decimal by dividing by 100)
632/.60=x
x= 1053.33
x is your original price
the actual answer is 1053.3333(3 repeating) but since it is money you cut it off at 2 decimal points.
That's a right triangle with hypotenuse 3000 and the height y is the side opposite the elevation angle of 15 degrees.

We can actually compute

exactly but I won't bother.
Graph B represents a proportional relationship.
