In ΔABC, a = 4 inches, b = 5.8 inches and ∠C=99°. Find ∠B, to the nearest 10th of an degree.

m∠B = 49.4°

Step-by-step explanation:

Use the law of cosines to get side c, and then the law of sines to get angle B

sin C/c = sin B/b

sin 99/7.543 = sin B/5.8

sin B = 5.8 sin 99/7.543

        =  .75945

m∠B = arcsin .75945 = 49.4°

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
