Answer:
YX < YW < XW
Step-by-step explanation:
12v +(v+57) + (v+39) = 180
14v + 96 = 180
14v = 84
v = 6
3 angles from smallest to largest: 72° (12v) (XW) , 63° (v+57)(YW) , 45° (YX)
side length: YX < YW < XW
Answer: 72
Step-by-step explanation:
A = bh
A= (12)(6)

You could separate the equation:
2*50+ 2*3=
I know that 2*50= 100; 2*3= 6
100+6= 106
I hope this helps!
