Answer:

x = 4 \sqrt{2}

y = 4 \sqrt{6}

Step-by-step explanation:

\sin 45 \degree =  \frac{x}{8}  \\  \\ x = 8  \sin 45 \degree \\  \\ x = 8 \times  \frac{1}{ \sqrt{2} }  \\  \\ x =  \frac{8 \sqrt{2} }{2}  \\  \\ x = 4 \sqrt{2}  \\  \\   \\  \tan 30 \degree =  \frac{x}{y}  \\  \\  \frac{1}{ \sqrt{3} }  =  \frac{4 \sqrt{2} }{y}  \\  \\ y = 4 \sqrt{6}

Pls help if you only know the correct answer! Thanks! :)

Answer:

A. -3/5 B. 1/5. C. 0.8.

Step-by-step explanation:

Since A is on the left side of 0, it will be negative, in which -3/5 is the only negative answer on there, so A= -3/5. Since B is on the right side of the 0 it's positive, and it is equal to 1/5 which gets you to 0.20, which will be the value of each line since 1 divided by 5 is equal to 0.20. 0.8 is also known as 0.80 so C will be next to the 1.
