so than this is a rectangle than 2x-10=90 so 2x = 100 so x = 50 and for y you can writing 3y +9 =90 so 3y = 81 so y = 27 

so this mean that choice B. is righ sure

Answer:

B. x=50, y=27

Step-by-step explanation:

Since we know that MNOP is a rectangle we also know that each angle equals 90°.

So now we do

2x-10=90           3y+9=90

+10     +10                -9   -9

2x=100                    3y=81

/2      /2                     /3  /3

x=50                          y=27
