2) Once you know how much each token costs, then multiply by 19 to get how much 19 tokens costs. (which is $10.45)

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
