Question

What is BC? Plz help

Answer 1

Answer and Step-by-step explanation:

To find the length of BC, we will be using the trigonometric function Sine.

The Sine trig function is as follows:

sin(θ) =
`(Opposite Side)/(Hypotenuse)`

Plug in the values and solve for the Hypotenuse (BC)

`sin(45) = (8)/(x)`

Multiply x to both sides, then divide both sides by sin(45).

x =
`(8)/(sin(45))`

Input into a calculator and solve.

The length of BC is
`8√(2)`, or 11.3137.
