Answer:

5.44 units

Step-by-step explanation:

We need to use trigonometry.

Notice that we want to find the side opposite the angle marked 65 degrees. We are given the length of the hypotenuse, which is 6. Suppose the length of the opposite side is x. So, we need to use sine, which is opposite ÷ hypotenuse:

sin(65°) = x ÷ 6

Multiply both sides by 6:

x = 6 × sin(65°) ≈ 5.44 units

sin65 = opposite/hypotenuse

sin65 = BC/6

BC = 6sin65

BC = 5.437846722

Describe two ways to graph the equation <br> y-1=3/2(x-4)
irakobra [83]
The given equation is in point-slope form.  The line that represents this equation passes through the point (4,1) and has a slope of (3/2).

One way to graph this quickly would be to plot the point (4,1).  Move 2 units to the right from this point, and then (without picking up your pen) 3 units up.  Plot a dot there.  Connect the 2 points with a straight line.
