Answer:
The measure of angle 6 is 72.
The measure of angle 7 is 108.
Step-by-step explanation:
Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.
If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.
- Slope formula:
So lines that are parallel will have the same slope. So the answer we are looking for will have the same slope as the line containing points (3,4) and (-2,2). Use the slope formula to determine which of these points have the same slope.
<h3>Original Line:</h3>
<u><em>Lines that are parallel to this line will have a slope of 2/5</em></u>
<h3>Option A:</h3>
<h3>Option B:</h3>
<h3>Option C:</h3>
<h3>Option D:</h3>
<h2><u>Results:</u></h2>
Since the only options that had a slope of 2/5 was options B and D, <u>B and D are your answers.</u>
39 degrees is the measure of the 3rd. Hope I helped. :) Please click thanks. :)
It is! When you're doing a fraction specifically like that, the denominators cancel out. Therefore you can get rid of the 12. It just becomes 21/7, which as you know is 3.
Hope that helps :)
