What is the value of x?

1 answer:

3 0

I thought it was 5 because the 55 degrees given is equal to the angle above it. If you look, there are 4, 90 degree angles so the 8x-5 has to equal 35 to make 90 but idk

Find the midpoint of the line segment with the given endpoints.<br> (-3,-7) and (3,0)

Crank

The coordinates of the midpoint:
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
x₁,y₁ - the coordinates of one endpoint
x₂,y₂ - the coordinates of the other endpoint

$(-3,-7) \\
x_1=-3 \\ y_1=-7 \\ \\
(3,0) \\
x_2=3 \\ y_2=0 \\ \\
\frac{x_1+x_2}{2}=\frac{-3+3}{2}=\frac{0}{2}=0 \\ \\
\frac{y_1+y_2}{2}=\frac{-7+0}{2}=\frac{-7}{2}=-3.5 \\ \\
\boxed{(0,-3.5)} - \hbox{the midpoint}$
