Destiny designs necklaces.
She uses between 15 and 20 yellow and blue beads in a ratio of 4 yellow beads to 5blue beads. What ratio is the requirement?

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

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
