OpenStudy (isuckatschool43):

I don't understand this question.

OpenStudy (foolofatook):

so. you must first know that the whole triangles total is 360. if you where to add together the three angles you have 360

OpenStudy (theprofessor35):

Exterior angles are on the outside. Interior is inside.

OpenStudy (foolofatook):

and the exterior angle minus the interior = 360

OpenStudy (foolofatook):

so a is 360-75

OpenStudy (isuckatschool43):

so 285?

OpenStudy (foolofatook):

o... i did this wrong... each angle is 180.

OpenStudy (foolofatook):

so sorry

OpenStudy (isuckatschool43):

oh yeah

OpenStudy (isuckatschool43):

so 105

OpenStudy (foolofatook):

but the equation now is 180-75

OpenStudy (isuckatschool43):

so c is 130

OpenStudy (foolofatook):

no. c is 105-50 because its a-50 and the variable a=105

OpenStudy (isuckatschool43):

oh

OpenStudy (isuckatschool43):

so 55

OpenStudy (foolofatook):

yes

OpenStudy (foolofatook):

no. c is 125

OpenStudy (foolofatook):

because its an exterior angle

OpenStudy (isuckatschool43):

ok

OpenStudy (isuckatschool43):

is B 130 @foolofatook

OpenStudy (foolofatook):

yes

OpenStudy (isuckatschool43):

OpenStudy (foolofatook):

OpenStudy (isuckatschool43):
