In the diagram above, suppose mz6= 115°. Explain how to find the measures of each of the other seven
numbered angles.
(Please check aswell)

Angles 6 and 7 are vertical angles, not alternate interior.

The same applies to angles 4 and 1, and angles 5 and 8 as well.

Any time you have two lines cross to form an X shape, the angles that are opposite one another are considered vertical angles and are always congruent.

The values you have typed into the boxes are all correct. The other drop-down choices are correct as well. Nice work.

From top to bottom:

Your mistakes are that you are confusing vertical angles with alternate-interior angles. Angles 6 and 7 for example are vertical angles while angles 3 and 6 are alternate-interior angles.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
