Question

GEOMETRY HW: In triangle ABC, 2B = 55, m2C = 100, and AC = 6. To the nearest tenth, what is the length of AB ?

Answer 1

Answer:

C   7.2 units

Step-by-step explanation:

Do you know the Law of Sines?  That's the only way I see to solve this problem.

6/sin 55 = AB/sin 100

AB = 6 sin 100/sin 55

AB = 7.2 units
