It is given in the question that,
George took a nonstop flight from Dallas to Los Angeles, a total flight distance of 1,233 miles. The plane flew at a speed of 460 miles per hour for the first 75 minutes of the flight and at a speed of 439 miles per hour for the remainder of the flight.
Let for x hours, the flight travelled with a speed of 439 miles per hour .
So we have,


And to convert it in minutes, we have to multiply by 60. And on doing so, we will get

It's 54 degrees.
The internet is a wonderful friend. Type in "Pentagon split into triangles" on google images and you will find a diagram that finds it.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, what are the coordinates of point Q and R. But I would show how to solve this.
The location of a point O(x, y) which divides line segment AB in the ratio a:b with point A at (
) and B(
) is given by the formula:

If point Q is at (
) and S at (
) and R(x, y) divides QS in the ratio QR to RS is 3:5, The coordinates of R is:

Let us assume Q(−9,4) and S(7,−4)
