Question

in triangle ABC, A= 65 degrees, and the measure of an exterior angle at C is 117. Find m 11 years ago

Answer 1

do you know what the question means by exterior angle?

Answer 2

yes, but I already found b which is 52, I just need help finding c.

Answer 3

i think i know how you found B but usually people find a and c THEN find b

Answer 4

if that is a line there which is 180 degrees
then C AND the exterior angle must add to become 180

Answer 5

so if C+117=180 then what is C?

Answer 6

ah, right, I forgot about that, so would it be 63?

Answer 7

yes

Answer 8

my next question is, in your math class do they teach you that A + B is equal to EXTERIOR ANGLE?

Answer 9

is that how you got b?

Answer 10

yes.
