Answer:
4b -11 = 1 -2(3-b) (use the distributive property on -2(3-b))
4b -11 = 1 -6 +2b ( combine like terms on the right side of the = sign)
4b -11 = -5 +2b (subtract 2b from both sides)
2b -11 = -5 (add 11 to both sides)
2b = 6 (divide each side by 2)
b= 3 ( so, your answer is C)
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.
Hello! I would love to help!
The answer is -10,-1
Basically, you have to fill -10 in for x and -1 in for y in each equation. If the equations are true, that is the right answer!
