Question

How do you determine the number of possible solutions using the rule of law of sines given a = 3 , b = 7, Alpha = 70 degrees?

Answer 1

No triangle is possible.

Explanation:

Using law of sines in this triangle ABC, `sinA /a= Sin B /b`, it would be `sin 70 /3 = sin B /7`. This gives `sin B=7/3 sin70 =2.1926`, which is obviously not possible.
