C(0,3) \\
x_1=0 \\
y_1=3 \\ \\
D(4,7) \\
x_2=4 \\
y_2=7 \\ \\
\overset{\underline{\ \ \ \ }}{CD} =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(4-0)^2+(7-3)^2}= \\
=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{16 \times 2}=4\sqrt{2} \\ \\
\boxed{\overset{\underline{\ \ \ \ }}{CD} = 4\sqrt{2}}

What does x = and why and how does that number come out
dedylja [7]

More algebra pretending to be geometry.  These questions should be banished from the planet.

A transversal across parallel lines generates the usual congruent and supplementary angles; here our pair are supplementary, adding to 180 degrees.  Geometry done.

(2x + 12.8) + 117.6 = 180

2x = 180 - (12.8 + 117.6) = 49.6

x = 49.6/2 = 24.8

Answer: 24.8
