The z-score is 3, because 294-210=84; 84/28=3

Answer:
Step-by-step explanation:
supplementary angles add up to 180
so let one angle be x.....and the other angle is 5 times bigger....so let the second angle be 5x
x + 5x = 180
6x = 180
x = 180/6
x = 30
5x = 5(30) = 150
so one angle is 30 and the other angle is 150
