Answer:

BC = 8 \sqrt{2}

Step-by-step explanation:

\sin(45)  =  \frac{opposite}{hypotenuse}

\sin(45)  =  \frac{8}{BC}

(BC) \sin(45)  =  \frac{8}{x} (BC)

(BC) \sin(45)  = 8

\frac{(BC) \sin(45) }{ \sin(45) }  =  \frac{8}{ \sin(45) }

BC =  \frac{8}{ \sin(45) }

BC = 8 \sqrt{2}

How to divide mixed numbers
aleksandr82 [10.1K]
You can of course use a calculator, but if you can't, just put them into improper fractions. So 2 3/4 as an example would be 11/4. So if you had 2 3/4 divided by 4 1/2, you'd have (11/4)/(9/2).
When you divide fractions, you can multiply by the reciprocal. So you'd go (11/4)•(2/9)=22/36=
11/18
