(x-1)(x-1) + (y+2)(y+2) = 3
x2 -1x -1x + 1 + y2 +2y +2y +4=3
x2 +y2 -2x +4y + 2=0
A is the answer
Answer:
60(a+b) means that you would have to distribute
While 60a+ 60b is already in it's simplest form
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.
Answer:
im gonna say it would be around 9 inches, because the actual answer, a decimal, isnt an option so the closest would be around 9 in.
