Question

I've got Trigonometry/Geometry, and I need someone to check my answers. Here they are:

|Given|
Circle N is equivalent to Circle M

a) Find m 11 years ago

Answer 1

For part a, your answer would be correct if we could assume that IMK is a diameter of circle M.

But they didn't tell us that :(
So we don't know for sure that that's a triangle, it might be a quadrilateral with a really large angle IMK.

Hmmm

Answer 2

@zepdrix That's what I was thinking, not to mention that my teacher wants me to be as specific as possible and to not assume answers. I need to score REALLY high on this if I'm going to pass this year since I'm failing and my teacher is being VERY lenient on me for late assignments. My year ends in a couple weeks as well.

Answer 3

Geometry is my worst subject :(
I don't know if I'll be of much help here, but I'll look at it a few more minutes, see if I can make sense of this.

Answer 4

@zepdrix Thanks.

Answer 5

@dan815 @jim_thompson5910 @freckles

Answer 6

Your part b looks great though.
Clearly LM is a radius of circle M.
And since both IM and MK are radii as well, then IK is just twice that length! :)

I wouldn't call it a diameter though, for the same reason as part a.

Answer 7

lol dayum thats a monster

Answer 8

a) is definately right

Answer 9

as IM is a radius then IK is a diameter therefore from inscribed angles

Answer 10

the angle at the edge is half hte andle from center
