Question 1189764

To solve triangle ABC(with angles A,B and C, sides a, b, and c, with side length la, lb, lc respectively)
(A) If A = 45°, la=7sqrt2, and lb=7 then there is one solution.
(B) If A=30°, la < Ib/2, then there is no solution.
(C) If A = 30°, la > Ib/2, then there are two solutions.
(D) All the above (A) (B) (C) are true.
(E) None of the above (A) (B) (C) is true.
Answer: D
Hey, I need help to solve this please, without a calculator, i solved the first and second one(by picking random values) but i cant solve the third one. How can i do it?
<pre>For C), if la > lb, then ONLY 1 triangle is possible. However, if lb > la, then 2 are possible.
There needs to be some other CLUE/INDICATION stating whether la or lb is LONGER.
