A spinner can land on red, blue or green. After 350 spins
relative frequency of red - 0.18
relative frequency of blue - 0.62
Work out the number of times the spinner landed on green.

what is the question here

step-by-step explanation:

the correct answer is the second option

what level of math? also i don't need to be paid if i can you.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
