okay so how many degrees is equal to a straight line?

OpenStudy (anonymous):

180˚

OpenStudy (egbeach):

good. so how would you find the angle of the obtuse angle?

OpenStudy (anonymous):

so 118˚

OpenStudy (egbeach):

you arent done yet... how many degrees are in a triangle?

OpenStudy (anonymous):

The answer would be 39˚?

OpenStudy (egbeach):

118 isnt the answer... once you know that you must subtract 118 and 23 from 180 to get 39. so yes you are correct
