Law of Sines:a/sin A = b/sin B = c/sin C Put in the values we know:a/sin A = 7/sin(35°) = c/sin(105°) Ignore a/sin A (not useful to us):7/sin(35°) = c/sin(105°) Now we use our algebra skills to rearrange and solve: Swap sides:c/sin(105°) = 7/sin(35...
1. Find the measure of side a. First we'll substitute the information we have into the Law of Sines: As you can see, we have enough information to find side a, but the last fraction is not helpful at all. Let's rewrite the law without it: Next we must solve the equation. ...
