Answer:2839.5
Step-by-step explanation:
Answer:
As described in picture:
RPS = 5x + 34
QPR = 8x + 15
RPS +QPR = QPS = 88
=>5x + 34 + 8x + 15 = 88
=> 13x + 49 = 88
=> 13x = 39
=> x = 3
=> RPS = 5 x 3 + 34 = 15 + 34 = 49 deg
Hope this helps!

Answer:
the diagonals bisect each other
Step-by-step explanation:
The midpoint formula tells you the midpoint M of segment XY is ...
M = (X + Y)/2
In your problem, the diagonals will bisect each other if they have the same midpoint. That is, we want to see if ...
(A +C)/2 = (B +D)/2
Multiplying by 2 can simplify our work a bit. In short, we want to test ...
A +C = B +D
(1, 4) +(-1, -4) = (4, -1) +(-4, 1) . . . . fill in the point coordinates
(1-1, 4-4) = (4-4, -1+1) . . . . . . . . . . simplify a bit
(0, 0) = (0, 0) . . . . . . . true, the midpoints are the same
The diagonals are mutual bisectors.
