Well this all the depends on what question is being asked.

OpenStudy (anonymous):

yah the question is asking to find the measurement of angle <ABC

OpenStudy (♪chibiterasu):

Ah, well I don't exactly remember this stuff from last year, sorry Dx

OpenStudy (anonymous):

can you write the full question please ?

hartnn (hartnn):

do you know what are vertically opposite angles ?

OpenStudy (anonymous):

3x-14=2x+10 -2x -2x 1x-14 = 10 +14 +14 1x=24 ________ 1 1 x=24

hartnn (hartnn):

wow! you nailed it ! :) now <ABC is just 3x-14 = 3(24) -14 =...?

OpenStudy (anonymous):

so all i do is times it

OpenStudy (anonymous):

so it would be 90

hartnn (hartnn):

3(24) -14 is not 90 .... did u get how its 3(24)-14 ??

hartnn (hartnn):

because <ABC is 3x-14 and x=24

OpenStudy (anonymous):

3(24)=72

hartnn (hartnn):

yup, 72-14 =... ?

OpenStudy (anonymous):

58

OpenStudy (anonymous):

hartnn (hartnn):
