Okay here it goes!

For your first question it will be acute and scalene. Because you have a degree that is smaller than 50 degrees and the triangle sides are all deferent sizes and that for they are scalene.
For your second question it will be 71 degrees. Because a triangle always has 180 degrees and if you have 38 degrees and 71 just add them and you would get 109 degrees and then you would subtract 180 - 109 an get 71 degrees!
Hope that helped!

Answer:

f(x) = (x -2)(x -1+3i)(x -1-3i)

Step-by-step explanation:

You can use synthetic division to find the remaining quadratic factor in the cubic. Then any of the usual means of solving the quadratic will help you find its linear factors.

In the attached, I show the synthetic division, the factoring to real numbers, and the solution that finds the complex linear factors by completing the square.

Of course, you know that for zeros a, b, and c, the linear factors are ...

f(x) = (x -a)(x -b)(x -c)

Here, we have a=2, b=1-3i, c=1+3i.

f(x) = (x -2)(x -1+3i)(x -1-3i)
