Answer:
1) A and D
2) C and D
3) Angle Y > Angle Z
4) OM, ON, MN
5) least: 7 cm, greatest: 23 cm
Step-by-step explanation:
1) angle C > Angle A > Angle B
If the lenth is greater, angle opposite is greater
2) If the lenth is greater, angle opposite is greater
3) XY is opposite angle Z
XZ is opposite angle Y
XZ > XY,
So Angle Y > Angle Z
4) Angle O = 180-54-61 = 65
5) 15 - 8.5 < third side < 15 + 8.5
6.5 < third side < 23.5
Least: 7
Greatest: 23
