Step-by-step explanation:
sin theta = opposite / hypotenuse
sin 45 = 6/x
Multiply by x
x sin 45 = 6
Divide by sin 45
x sin 45/ sin 45 = 6 / sin 45
x = 6/ sin 45
x = 6/ (1/sqrt(2))
x = 6 sqrt(2)
Answer:
This is a line with 2 points (0,0) and (1,55)
A folder costs 1.15 more than a pen, so a pen is x, folder is x+1.15
COST = 6x + 3(x + 1.15)
An equation for this problem is
Cost = number of pens(x) + number of folders (x + 1.15)
