Hunter-Best [27]3 years ago
6 0

Answer:

cos57° = x/51

General Formulas and Concepts:

<u>Trigonometry</u>

  • [Right Triangles Only] sin∅ = opposite over hypotenuse
  • [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use trig to solve for the missing side length.

<u>Step 2: Set up ratios</u>

We can choose between the 2 angles and have multiple ratios to solve for <em>x</em>.

sin33° = x/51

cos57° = x/51

Hence, we see that the 1st option would be the correct answer.

the mean of a set of five numbers is 3k. when a sixth number is added to the set, the mean increases by k. what is the ratio of
Strike441 [17]

Let’s call the sum of the set of five numbers S and the sixth number N. We know the mean of the set of five numbers is 3k, so we can write the equation S/5 = 3k or S = 15k. When we add the sixth number the mean increases by k, so we can write the equations (S + N)/6 = 4k or S + N = 24k. Using S = 15k, we find that N = 9k. The ratio of the sixth number to the sum of the set of five numbers is therefore N/S = 9k/15k = 3/5.
