So there are 2 angles. Supplementary and complimentary... Supplementary is 180 degrees and complimentary is 90 degrees. This means you will go and do,
180-41.4
90-41.4
So the way the question is worded, list the complimentary first!
Now go and get the answer for both and put them in the right order! (that is important)

Answer:
0.0403
Step-by-step explanation:
Given that 76% of americans prefer coke to pepsi.
Let x be the number of people who prefers coke to pepsi.
X is binomial as each trial is independent, and there are only two outcomes.
A sample of 27 was taken.
We have to find the probability that less than sixty percent of the sample prefers coke to pepsi
60% of 27 = ![27(0.6) = 16.2](https://tex.z-dn.net/?f=27%280.6%29%20%3D%2016.2)
Required probability = ![P(X](https://tex.z-dn.net/?f=P%28X%3C16.2%29%20%5C%5C%3DP%28X%5Cleq%2016%29%5C%5C%5CSigma%5E16_%7Br%3D0%7D%2027Cr%280.76%29%5Er%20%280.24%29%5E%7B27-r%7D)
Hence prob=0.0403
Answer:
19
Step-by-step explanation:
4 × ( 3/ 4 − 1/ 2 ) + 3 × 6
PEMDAS
Parentheses first
4 × ( 3/ 4 − 2/4 ) + 3 × 6
4 × ( 1/4 ) + 3 × 6
Then multiply and divide from left to right
1 + 18
