• I still don't fully understand this is there another video to help me?
• For some reason, whatever the number is on the other side is your answer
• you may never use them. But it's good to learn them, just in case an everyday problem comes up that involves angles. You'll be able to solve it and help everyone else out because you saw that video on Khan Academy in 7th grade. :)
• Who would remember this
• I have no idea how to do this. I feel so stupid. How do I find the value of the angles? Every time I type out an answer, it ends up being an answer that was right in front of me the whole time. Can someone help me?
• I don't really understand this either, but there's no need to feel stupid. Don't get down on yourself. I will gladly help you, but I don't really understand what you need help with. I understand that you don't get it, but what don't you get?
• I'm so confused. How do we fine the remaining angles?
• i sill dont understand this or how to do it? so what do i do
• I'm confused someone explain it all to me
• So Basically, 60 degrees + x = 7x, so if you subtract the x on both sides , you get 60 = 6x, because x = 1x ! The whole area is 70 degrees, and 7x is 70 divided by 7, which is 10 ! So x is 10 !

• my work is saying onward to where i could not do it.
