Ready when you are

Shadow:

hardlyhuman:

okay

hardlyhuman:

so inscribed would be 38?

hardlyhuman:

wait uhhh, sort of confused

Shadow:

http://prntscr.com/j20lhq They want this.

hardlyhuman:

okay

Shadow:

\[Inscribed Angle = \frac{ 1 }{ 2 } Arc\] We solve for XZ, subtract it from 360, and get XYZ. Makes sense?

hardlyhuman:

yes

Shadow:

What is our inscribed angle?

hardlyhuman:

let me see

hardlyhuman:

XYZ sorry i was getting water

hardlyhuman:

and XYZ=76

Shadow:

Inscribed Angle XYZ with a measure of 76 degrees intercepts the arc XZ. How do we solve for XZ?

hardlyhuman:

hold please

hardlyhuman:

would i find the answer to that in my last post btw?

Shadow:

Likely not

Shadow:

Well, technically yes. But I gave the formula here.

hardlyhuman:

okayy

hardlyhuman:

okay i dont know

hardlyhuman:

would it be 152?

Shadow:

\[InscribedAngle = \frac{ 1 }{ 2 }Arc\] Could also rewrite it as \[2 \times InscribedAngle = Arc\]

hardlyhuman:

yea i just found that again XD

Shadow:

That's arc XZ. Good job. What do we do now?

hardlyhuman:

152 - 360 = 208

Shadow:

Bingo

hardlyhuman:

yay

Shadow:

Just maybe subtract the other way, otherwise It would be -208. So 360 - 152 = 208

hardlyhuman:

okay, thank you. if your up to it could we do the next one?

Shadow:

Sure

hardlyhuman:

thank you
