Answer:

x = 5.1

Step-by-step explanation.

Our first step is to find all the angles. If b = 91 degree and c is 38, a. has to be 51 because all triangles add up to 180 degree. Because we have both B and b, we can use sine law.

a/A 13/sin91 c/38

we can use b in this situation.

The legnth of a is 10.1.

So, x-5 would be 5.1

Answer:

B. 0

Step-by-step explanation:

If you subtract the right side expression and simplify, you get ...

4/5(20x +5) -(16x -2) = 0

16x +4 -16x +2 = 0

6 = 0 . . . . . . . . . . . . false

There is no value of x that will make this true. There are no solutions.
