We are getting shmoopy with it.
- 00:04
In the following diagram lines A&B are parallel Plan C is perpendicular angle
- 00:09
four measures the 105 degrees what his angle 15 measure
- 00:13
Hear the potential answers...Pausing.
- 00:17
Well it just want to make sure we have a basic understanding of angles.

In our diagram were only told the measure of angle 4
- 00:24
So how does that get us to 15? Well if we know about
- 00:28
vertical angle we should know that angle 7
- 00:32
the one opposite angle 4 is also 105 degrees
- 00:35
Next because we're told a and b are parallel we should realize that angle 7 and 15
- 00:41
would have the same measure.
- 00:43
So our answer is D.
