Sin C = AB / AC
We have AC. We need to calculate AB

ABC is a right triangle. Therefore, AC² = AB²+BC²
82² = AB ² + 80² => AB² = 82² - 80²
AB = 18

Sin C = 18/82 = 9/41

Good luck

Answer:

Median = 13

Step-by-step explanation:

We are given the following data:

16, 15, 13, 12, 17, 14, 11, 9, 11

Formula:

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Sorted data: 9, 11, 11, 12, 13, 14, 15, 16, 17

Median =

=\dfrac{9+1}{2}^{th} = 5^{th}\text{ term} = 13

Thus, the median of the given data is 13.

What is the volume of A cube with the surface area of 600 in.²
GrogVix [38]

Answer:

1000 in³

Step-by-step explanation:

A cube has 6 square faces

Given the surface area of the cube = 600 in², then

The area of 1 face = 600 ÷ 6 = 100 in²

The area of a square = s² ( where s is the measure of a side ), thus

s² = 100 ( take the square root of both sides )

s = \sqrt{100} = 10

The volume (V) of the cube = s³, so

V = 10³ = 1000 in³
