Just clarify if i have to use x = 1/2(mAB +mCD) to solve it
mathstudent55
  • mathstudent55
Yes, here it is (1/2)(mVW + m XZ), with VW = 43, and XZ = 94

Thanks, now i feel more confident about doing these types of problems.

  • mathstudent55
Can we go back to your previoous problem of this type? I misread it.

I saw the Y inside the circle and was thinking of the measure of the angle that has y inside it. I misread the problem.

This is what your problem looks like. |dw:1370308719629:dw|

Got it

You are asked to find the measure of angle XYZ. |dw:1370308846808:dw|

I'm going be mad if i did have to end up dividing the outer degree by 2
anonymous
  • anonymous
Was my answer suppose to be 43 degrees ?
mathstudent55
  • mathstudent55
This angle is found directly using the formula we used: m
mathstudent55
  • mathstudent55
The answer is the measure of anfle XYZ is half the sum of the two arcs, so m

Oh it was x instead of y

It's fine we are only human.
mathstudent55
  • mathstudent55
Right. All we were looking for was what I called x. And x was 65.

You are correct.

I have a two more i need help with is that fine ?
mathstudent55
  • mathstudent55
sure
anonymous
  • anonymous
I get confused right here is the outer degree the same as the other side or is there something i have to do to get the result ?

You need again the formula we've been using. 42 = (1/2)(38 + mXY)
anonymous
  • anonymous
Are you 100% Positive ?
mathstudent55
  • mathstudent55
yes
mathstudent55
  • mathstudent55
Did you get an answer?
anonymous
  • anonymous
I divide 38 ? then i subtract the rest from 42 ?
anonymous
  • anonymous
I did but i'm not sure i'm right
anonymous
  • anonymous
mXY = 23
mathstudent55
  • mathstudent55
42 = (1/2)(38 + mXY) First, multiply both sides by 2 to get rid of the the 1/2 on the right side: 84 = 38 + mXY Now subtract 38 from both sides

46

right

I thought it was going to be different but it's similar to the first one, thank you so much though and go enjoy your life (: .
