Explanation:
To find x we need to find the unknown side that connects the two triangles using the Pythagorean theorem:
a² + b² = c² (c is always hypotenuse)
So:
a² + 6² = 9²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = sqrt45
Now we do the same thing for the other triangle:
x² + 5² = sqrt45²
x² + 25 = 45
x² = 20
x = 2√5 or 4.5...

Answer:
15. the answer is "Omar would have 3 cups of cornmeal left"
Step-by-step explanation:
this is because you have 5 cups of cornmeal, you need to make 24 muffins and 1/2 of a cup makes 6 muffins. 24 divided by 6 equals 4 and 1/2 times four equals 2. therefor, you would only need 2 cups of cornmeal to make 24 muffins, which in the end leaves him with 3 cups left.
