The answer should be 6f. You multiply the 3 and the 2 and then put the f at the end (:
I’m not sure about number 9. But number 10 is answer C. This is because there are two sides to a coin, so you are equally likely to land on heads as you are tails. So you take 64 and divide it by 2, and get the answer 32.
Answer:
Step-by-step explanation:
take angle C as reference angle
using cos rule
cos C=adjacent/hypotenuse
cos C=21/75
cos C=0.28
C=
0.28
C=73.7 degree
15 degrees below zero = -15
25 degrees above zero = 25
25 + 15 = 40
It rose 40 degrees.
