Answer:
6.7 cm
Step-by-step explanation:
To make use of the Law of Sines for finding b, you need to know the missing angle B. Since the sum of the angles of a triangle is 180°, you can find angle B as ...
B = 180° -82° -55° = 43°
Now, you put the numbers you know into the formula given and solve for b.
sin(A)/a = sin(B)/b
sin(55°)/(8 cm) = sin(43°)/b
Cross multiplying gives ...
b·sin(55°) = (8 cm)·sin(43°)
and dividing by the coefficient of b gives you ...
b = (8 cm)·sin(43°)/sin(55°) ≈ 6.7 cm

7. No, the associative property does not work for subtraction or division, they do not hold for the associative property. For example,
2+ (3+4) = (2+3) + 4 2- (3-4) = (2-3) – 4
2+7 = 5+4 2 + 1 = -1-4
9 = 9 3 = -5, which is not true
8. No, the commutative property does not work for subtraction or division, they will give a different result. For example,
5+6 = 6+5 5-6 ≠ 6-5
