Best ResponseYou've already chosen the best response.0Given:<SRT is congruent to <STR, m<SRT=20, m<STU=4x

Best ResponseYou've already chosen the best response.1ok, you need to know that the sum of the three angles in any triangle is 180 and the sum of the angles that make up a straight line is also 180

Best ResponseYou've already chosen the best response.0Yes, I get that but how do I put that into this problem?

Best ResponseYou've already chosen the best response.1They say SRT and STR are congruent, or the same angle, and they tell you one of the values

Best ResponseYou've already chosen the best response.0okay so would 4x=140

Best ResponseYou've already chosen the best response.1Angles that make up a straight line total 180, supplimentary angles STU + STR = 180

Best ResponseYou've already chosen the best response.0okay so instead of looking at this like a triangle I should look at this like its two angles that are supplementary?

Best ResponseYou've already chosen the best response.1you can look at it a few different ways, the short way i just did it was to realize STU + STR = 180 20 +4x = 180 4x = 160 x = 40

Best ResponseYou've already chosen the best response.1or if you want to use the fact that all 3 angles in a triangle add to 180 you can draw this ...

Best ResponseYou've already chosen the best response.0but wouldn't it be 40+4x=180?

Best ResponseYou've already chosen the best response.0oh wait I see because your only involving one of the angles, thanks!!!

Best ResponseYou've already chosen the best response.0yeah that looks confusing but thanks I got it now!!!

Best ResponseYou've already chosen the best response.1yeah, or you can draw that second line parallel to U, and use alternate interior angles are equal, the transversal is ST
