D
x = 21°
Vertical angles have the same measures, therefore:
3x - 30 = 2x - 9
x - 30 = -9
5/12
Assuming the each number is equally likely
1,2,3,4,5,6,7,8,9,10,11,12
There are 12 numbers on the spinner
Number less than or equal to 5: 1,2,3,4,5
There are 5 choices
P ( # < = 5) = Number less than or equal to 5/ total
=5/12
