Answer:

8x - 24 + 4x = 180

12x - 24 = 180

12x - 24 + 24 = 180 + 24

12x = 204

12x / 12 = 204 / 12

x = 17

∠NOP = 4(17)

= 68°

Answer:

it might not be on the choice but i got 38.

Step-by-step explanation:

since MNOP is a cyclic quadrilateral it's opposite sides are complementary. so

8x-24+4x=90

12x-24=90

12x=90+24

12x=114  (divide both sides by 12)

x=9.5

since you asked for<NOP=4*9.5=38.
