axie:

based off that what do we know?

Sailor:

subtract the missing angle by 90?

minustempo:

no you can't assume the angle is 90 degrees

axie:

and what would that math problem look like? We have x-90=angle

Sailor:

would it be 110?

minustempo:

You need to use the inscribed angle theorem and Thales' theorem

minustempo:

So the degree of the minor arc JV is 110 degrees, which is given. Based on the inscribed angle theorem, can you figure out what angle JKV is?

minustempo:

Also, Thales' theorem is that if you have a triangle in a circle where the hypotenuse is the diameter, then the triangle is a right triangle

minustempo:

Which means you know angle JKL is 90 degrees.

Sailor:

Ok now im even more confused ;u;

Sailor:

sorry this teacher went on maternity leave so ive pretty much hit a math roadblock

minustempo:

I will show a screenshot of thales' theorem

minustempo:

Sailor:

So theres only one triangle i need?

minustempo:

Pretty much

minustempo:

Do you know how to find angle JKV?

Sailor:

Is it x-110=90?

minustempo:

You cannot assume that the angle of the smaller triangle is 90 degrees. 1. because the problem didn't say KV and JL perpendicular 2. they don't even look perpendicular

Sailor:

Oh

minustempo:

Does it make sense though right now

Sailor:

A little

minustempo:

well here's what the degree of the arc means (attached)

Sailor:

so the missing angle would be 110 minus something?

minustempo:

Well the answer is 90-(110/2) = 35
