Answer: 
Step-by-step explanation:
We need to use the following formula to find the Midpoint "M":

Given the points (-5,13) and (6,4) can identify that:

The final step is to substitute values into the formula.
Therefore, the midpoint of the segment between the points (-5,13) and (6,4) is:

the value of x is 36 degree
