Answer:
2.0 cm
Step-by-step explanation:
The sum of ratio units is 11 +5 +2 = 18, so each one stands for 10° of angle. Then the largest angle is 110°, and the smallest is 20°. The law of sines can help us find the smallest side (x):
x/sin(20°) = 5.5/sin(110°)
x = 5.5·sin(20°)/sin(110°) ≈ 2.00
The side opposite the smallest angle is 2.0 cm.
