Jamal is playing a card game with his friends. the deck has red and black cards numbered 1-12. red cards represent negative numbers, black cards represent positive numbers. if he needs a product of 24, what are the possible combinations of cards jamal could use?

First let us assume all black cards, the numbers that will result in 24 is:

2 * 12

3 * 8

4 * 6

Similar case with the red cards:

-2 * -12

-3 * -8

-4 * -6

Assuming the product can be negative, so we can also take the combination of two cards (1 red and 1 black):

2 * -12

3 * -8

4 * -6

-2 * 12

-3 * 8

-4 * 6

 

So there are a total of 12 combinations.

Step-by-step explanation:

Step 1: Identify

Angle θ = 39°

Opposite Leg = 30

Adjacent Leg = x

Step 2: Solve for x
