The angles shown are
PR is the bisector of angle P
So
So the X coordinate is 4, and the Y is -5. The rule says X + 2, Y - 8 so (4) + 2, (-5) - 8.
It's D (6, -13)
Here let us first write the value of each number:
6 thousands means 6*1000=6000.
9 hundreds means 9*100=900.
12 tens means 12*10 =120
10 ones means 10*1 =10
3 tenths means 3/10 =0.3
Now we just have to add all these values to get the final number.
adding 6000 + 900 +120 +10 +0.3 = 7030.3
So the final number is 7030.3
