The answer is D.-12 hope this helps.
According to the law of sines:
Using the given values, we can find the angle B and find the number of possible triangles that can be formed.
The range of sin is from -1 to 1. The above expression does not yield any possible value of B, as sin of no angle can be equal to 1.45.
Therefore, we can conclude that no triangle exists with the given conditions.
2 because the equation can be reduced to: 8.0 x 10^4.
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have
and the modulus would simply be
. Since
we would expect the final product to fall in the first quadrant.
