1 answer:
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.

Write an equation of a line in point-slope form with the
Ulleksa [173]

Answer: (y − 0) = -(1/6)(x − 6)  or y=-(1/6)(x-6)

Step-by-step explanation:

An equation in Point Slope form:  y − y1 = m(x − x1), where m is the slope and x1 and y1 are provided as a single point, (x1,y1).  We have slope(m) = -(1/6) and are given (6,0).  Therefore:

 (y − 0) = -(1/6)(x − 6)  (Point slope form)

y = -(1/6)(x-6)

Rewriting this into standard form, y = mx + b

y = -(1/6)x + 1
