Triangle ABC is congruent to triangle XYZ. Angel A measures 50 degrees. Angle B measures (2x+40) and angle Y (4x+8). Find the value of x.
How do I set this up proportionally?

Best ResponseYou've already chosen the best response.0you can make C = z then you know that all interior angle triangle angles add up to 180

Best ResponseYou've already chosen the best response.0Triangle ABC is similar to triangle XYZ. Side AB measures 2, side BC measures x + 5, side CA measures x + 7, side XY measures 4 and side ZX measures 4x – 2. Find the value of x. I'll give with it simplified and the fraction, that way I can't be wrong.

Best ResponseYou've already chosen the best response.0looks good to me.simplify the leftside and then multiply both sides by x+5 to get rid of the deonominator on the right

Best ResponseYou've already chosen the best response.0or you could just "cross multiply" but that's unnecessary and not actually a technique technically
