The triangle ABC is a right triangle

The length of AC is 12.00 cm

<h3>How to determine the length of AC</h3>

From the figure, we have the following parameters:

Length AB = 13 cm

Angle A = 22.6 degrees

Represent the length AC with b.

So, we have the following cosine ratio

\cos(A) = \frac{b}{AB}

Substitute known values

\cos(22.6) = \frac{b}{13}

Make b the subject

b = 13 * \cos(22.6)

Evaluate the product

b = 12.00

Hence, the length of AC is 12.00 cm

Vlad1618 [11]
The answer is 30 cups

Let x be a multiplier. So:
2x + 5x + 9x = 96
16x = 96
x = 96/16
x = 6 cups

Since the number of onion cups is 5x, then 5 * 6 = 30 cups are needed to make 96 cups of salsa.

Step-by-step explanation:

Let's solve for x.

2y+5x=4

Step 1: Add -2y to both sides.

5x+2y+−2y=4+−2y

5x=−2y+4

Step 2: Divide both sides by 5.
