Question?

OpenStudy (twizttiez):

Oh i have the app on my phone and i took a picture of the ? i guess it didn't come up

OpenStudy (twizttiez):

Determine the measure of each exterior angle. The measure of angle A is °. The measure of angle B is °. The measure of angle C is °.

OpenStudy (twizttiez):

Does that help?

OpenStudy (twizttiez):

@sleepyjess

OpenStudy (sleepyjess):

I actually will be in and out for about 30 mins, but if you haven't gotten help by then, I will help you :)

OpenStudy (twizttiez):

Oh ok then thanks

OpenStudy (sleepyjess):

Actually, let's see how much of this we can get done in the next 10 minutes :)

OpenStudy (twizttiez):

Ok that sounds good :)

OpenStudy (sleepyjess):

Ok, you said you are on the app right now?

OpenStudy (twizttiez):

And on the computer they are both open

OpenStudy (sleepyjess):

oh ok, thank goodness

OpenStudy (twizttiez):

Lol ok

OpenStudy (sleepyjess):

This would have been really hard to do without drawings haha

OpenStudy (sleepyjess):

Ok, so exterior angle A + 75 must equal to 180

OpenStudy (twizttiez):

I does work pretty good on the 6 though i like it

OpenStudy (twizttiez):

But onwards lets get this over with

OpenStudy (sleepyjess):

Yes, but you can't see drawings on the app, which sometimes makes it really difficult to walk someone through a problem that requires drawings.

OpenStudy (twizttiez):

Ohh ok i gotcha

OpenStudy (twizttiez):

@mathmate

OpenStudy (sleepyjess):

Did you see what I had said about angle A?

OpenStudy (twizttiez):

Yeah 180

OpenStudy (sleepyjess):

Yep, so what is angle A?

OpenStudy (twizttiez):

The exterior is 180 whilst the interior of A would be 75 right

OpenStudy (sleepyjess):

No, the exterior angle + the interior angle of 75 must add to 180

OpenStudy (twizttiez):

255

OpenStudy (sleepyjess):

??? 180 - 75 = exterior

OpenStudy (twizttiez):

105

OpenStudy (sleepyjess):

yes

OpenStudy (sleepyjess):

ok, I will be back in like 15 mins :)

OpenStudy (twizttiez):

k

OpenStudy (mathmate):

|dw:1424289369722:dw|

OpenStudy (mathmate):

So A, B and C are exterior angles of the triangle.

OpenStudy (mathmate):

The important hint is "angles on a line add up to 180 degrees (or are supplementary)." |dw:1424289545502:dw| We can therefore say 50+X=180 and can solve for X=180-50=130 degrees. @TwiztTiez
