Answer:

Step-by-step explanation:
300 degrees is in the fourth quadrant (it's between 270 and 360); sine is negative in the fourth quadrant.
Given we're in the fourth quadrant, the reference angle is 360 - 300 = 60 degrees
sin(60°) =
And since sine is negative, this value turns negative:
sin(300°) = 
I don’t think so but I could be wrong
Length (L): 4w - 3
width (w): w
Perimeter (P) = 2L + 2w
34 = 2(4w - 3) + 2(w)
34 = 8w - 6 + 2w
34 = 10w - 6
40 = 10w
4 = w
Length (L): 4w - 3 = 4(4) - 3 = 16 - 3 = 13
Answer: width=4, length = 13
