-We already know TY is congruent to YZ
-because ZY and WY are a linear pair, we know they’re supplementary making angle TYW 90 degrees (aka congruent to angle WYZ)
-since triangle WYT and WYZ share a common side we know they are congruent there (due to the reflexive property)
-because of these three things the triangles are congruent by side angle side (SAS)
-because the two triangles are congruent, CPCTC says that WZ is congruent to WT
-this makes 2x= 3x-5
-simple algebra says that x=5
-5*2 = 10
ANSWER: TW=10
