Rania is playing with her friend Arun, and they are setting up dominoes across the room. Each domino is 2 inches long. They have already placed 10 dominoes in a row. The room is 10 feet long and they want to know how many more dominoes they can set up before they reach all the way across the room. Does the inequality 2d + 20 < 120 model this situation? Explain why or why not.

no

Step-by-step explanation:

It should be less then or equal too, seeing as they want to reach all the way across the room.

one of each metals

step-by-step explanation:

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
