Use the law of sines to solve the triangle, if two solutions exist, find both. A= 58 a=11.4 b=12.8

B=80.71 ,C=41.29,c=8.56

Step-by-step explanation:

Based on  Law of sines solution is given the photo

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
