Question

How many solutions does a triangle with side lenths a=4 a=112 deegrees and b=9have

Answer 1

0

Explanation:

apex use the number form!!!

Answer 2

It has no solutions.

Using the Law of Sines, we set up:

`(sin(A))/(a)=(sin(B))/(b) \\ \\(sin(112))/(4)=(sin(B))/(9)`

Cross multiplying, we have:
9 sin 112 = 4 sin B

Divide both sides by 4:

`(9sin(112))/(4)=(4sin(B))/(4) \\ \\(9sin(112))/(4)=sin(B) \\ \\2.086 = sin(B)`

Since sine runs from -1 to 1, we know that there is no angle with a sine greater than 1. This means there is no solution.
