calculate the side lengths a and b to two decimal places.

a. a = 11.40 and b = 13.38

b. a = 11.71 and b = 15.56

c. a = 4.18 and b = 3.15

d. a = 10 and b = 14

b

* In ΔABC

∵ m∠A = 45°

∵ m∠B = 110°

∴ m∠C = 180 - 45 - 110 = 25°

By using the sin Rule

∵ a/sin(A) = b/sin(B) = c/sin(C)

∵ c = 7

∴ a/sin(45) = b/sin(110) = 7/sin(25)

∴ a = (7 × sin(45)) ÷ sin(25) = 11.71

∴ b = (7 × sin(110)) ÷ sin(25) = 15.56

∴ The answer is (D)
