Answer:
Answer B: 10.12
Step-by-step explanation:
Let the numbers be represented by a, b and c. Their sum is 44.84. The number a is 24.6. Further, assume that b = c.
Then 24.6 + b + b = 44.84.
Let's isolate 2b:
Subtract 24.6 from both sides of this equation, obtaining:
2b = 20.24.
Finally, divide both sides of this equation by 2. We get b = 10.12.
This corresponds with Answer B.

Answer:
I believe this is pathgorean theorem, which I did at the beginning of alegbra last year. It is basically finding the missing side of a triangle. (Trust me some of the easiest stuff you do all year) Below are my notes from last year. I hope it helps! Good Luck!!!
Step-by-step explanation:
Given two sides
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
Answer:
x=3
Step-by-step explanation:
2x+3=9 (subtract 3 from both sides)
2x=6 (divide both sides by 2)
x=3
Y = a sin b x
amplitude = a
period = 2π /b.
<span>y = 6 sin x
a = 6
b = 1
</span>
a, the amplitude, represents the highest point a graph reaches;
a = 6
The period represents the length of a cycle-
the period = 2π /b = 2π/1 = 2π
