Second, simplify. / Your problem should look like:
![-34.7](https://tex.z-dn.net/?f=-34.7)
Answer:
A) -34.7
Answer:
Step-by-step explanation:
substitute x = r*cos(θ), y = r*sin(θ) ==> r²(cos²(θ) + sin²(θ)) = 2r²cos(θ)sin(θ). Cancel the r² on both sides. On the left, use pythagorean identity cos²(θ) + sin²(θ) = 1. On the right apply double angle identity sin(2θ) = 2cos(θ)sin(θ).
This yields 1=sin(2θ). (I assume you meant to type sin(2θ) on the right hand side of the equation).
1.6 cm would be your answer!
19 feet
convert 2
into an improper fraction
2
= ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
hence the length of the wall is 19 feet
Hm i think it might be 2:8?
