Answer:

He set the factored expressions equal to each other.  instead of setting them equal to zero

Step-by-step explanation:

f(x) = x^2 + 4x + 3. His work is shown below.

0 = x^2 + 4x + 3

0 = (x + 3)(x + 1)

Here is where we use the zero product property

x+3 = 0   x+1 =0  We do not set them equal to each other

URGENT! Please and Thanks :)

For this case we will define the following:
 A, B: are the values of the triangle angles
 a, b: are the values of the lengths of the sides opposite the angles A, B.
 We then have to use the law of the sine:
 \frac{sinB}{b} = \frac{sinA}{a}
 Clearing the angle B we have:
 sinB = \frac{sinA}{a}*b
 B = arcsin(\frac{sinA}{a}*b)
 Substituting values we have:
 B = arcsin(\frac{sin113}{200}*134)
 B = 38.08
 Answer:
 
the following is true:
 
A. angle B=38.08 degrees
