Did you see that angles QNS and RNS are a linear pair?

yes

Trick question. You should not see that because we are not told that.|dw:1441039192569:dw| Definition of bisector. What can we say about the measures of the two angles created by the bisection?

Haha good one, and I have no clue.

bisect
tkhunny

Right. And what does "bi" mean in this case?
anonymous
  • anonymous
dived into two parts
tkhunny
  • tkhunny
Two EQUAL parts. The measures of the two angles are equal. Now what? We are given the measures of the two angles.
anonymous
  • anonymous
Yes. (2x+15) and (6x-15)
tkhunny
  • tkhunny
It says "57" above. Which is correct. Anyway, you are nearly done. 2x+15 = 6x-15 Solve or x. This will not quite complete the assignment.

So I add 6x and 2x and I get 8x. or do I subtract them???
tkhunny
  • tkhunny
No. You must solve using normal procedures. Don't get jumpy. Subtract 2x from both sides.
anonymous
  • anonymous
how do you know if you subtract or add
tkhunny
  • tkhunny
You need to create zeros. 2x +15 = 6x - 15 Subtract 2x 2x - 2x +15 = 6x - 2x - 15 0 +15 = 4x - 15 Or just 15 = 4x - 15 Now, add 15. It should create zero, somewhere.
anonymous
  • anonymous
yes I got that
anonymous
  • anonymous
then aren't you left with 4x
tkhunny
  • tkhunny
You must be more careful. 15 = 4x - 15 Add 15 15 + 15 = 4x - 15 + 15 30 = 4x - 0 30 = 4x Now, divide by 4. Be careful.
