can someone help me

OpenStudy (anonymous):

Sure

OpenStudy (lpruitt4):

ok

OpenStudy (anonymous):

umm question?

OpenStudy (lpruitt4):

its right there in the picture

OpenStudy (anonymous):

Umm I'm not seeing any picture

OpenStudy (lpruitt4):

do you see it

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

it's definietly not A because 180/3 will give you the interior angles, not the exterior angles

OpenStudy (anonymous):

Do you know the degree measure of a straight line?

OpenStudy (anonymous):

^ A is not correct So how many degrees are each of the interior angles in an equilateral triangle?

OpenStudy (lpruitt4):

So is it c

OpenStudy (anonymous):

Yep :)

OpenStudy (anonymous):

no, not quite. 180* is the degree measure of the line. You have part of the measure, so by subtracting the interior angle from the line's angle, you can find the exterior angle.

OpenStudy (anonymous):

Oh sorry it is not C I got my answers mixed up

OpenStudy (anonymous):

Think of it this way This is an equilateral triangle meaning all the angles are equal

OpenStudy (anonymous):

So it's just total degrees in a triangle ---------------------- number of angles(3) Right?

OpenStudy (lpruitt4):

its not right

OpenStudy (anonymous):

And as @Madison2017 said it's a straight line so a straight line has 180 degrees in it Subtract the number of degrees in one of the interior angles from 180 and you would have the answer

OpenStudy (lpruitt4):

b

OpenStudy (anonymous):

yupp

OpenStudy (lpruitt4):

is this right

OpenStudy (anonymous):

yess
