Answer:

angle WXU=56 degrees

Step-by-step explanation:

WX || TV so angle WXU is congruent to angle TVU

68-3x=84-7x

simplify by adding 7x to each side

68+4x=84

simply further by subtracting 68 from each side

4x=16

divide both sides by 4

x=4

angle WXU=68-3x

substitute for x

angle WXU=68-3(4)=68-12=56 degrees
