Determine which lines are parallel
Bingel [31]

To do this, we must find the supplementary angle to those that are given.

The supplementary angle to 152 is 28, 54 is 126, 28 is 152, and 146 is 34

As 152 is 28, and 28 is 152, they are parallel,

So the answer would be lines e and g are parallel

PLEASE PLEASE HELP WITH THIS
Phoenix [80]
Since triangles ABC and BCD are similar, we can establish a proportion between the lengths of corresponding sides:
\frac{AC}{BC} = \frac{BC}{CD}

We can infer from our picture that BC=m. Also we can find the length of AC by adding AD and CD:
AC=AD+CD
AC=11+7
AC=18

Lets replace the values in our proportion:
\frac{AC}{BC} = \frac{BC}{CD}
\frac{18}{m} = \frac{m}{7}
Solving for m:
m^2=(18)(7)
m^2=126
m= \sqrt{126}

We can conclude that the correct answer is: D \sqrt{126}
