Answer: Choice C
XY < YZ < ZX
=================================================
Step-by-step explanation:
Check out the diagram below
Angle X = 70
Angle Y = 88
Z is the unknown angle. The three angles of any triangle always add to 180
X+Y+Z = 180
70+88+Z = 180
Z+158 = 180
Z = 180-158
Z = 22
Angle Z is 22 degrees.
Since Z is the smallest angle, this means the side opposite that is the smallest side. The smallest angle is always opposite the smallest side, and vice versa. So XY is the smallest side.
The largest side is always opposite the largest angle. Here we have angle Y = 88 as the largest, so side ZX is the largest side.
The order of the sides from smallest to largest is
XY < YZ < ZX
