Start with the small triangle on the right:

35 + 96 + x = 180

x = 49

Ah, you already have that. Nice!

Now move to the biggest triangle:

x + 77 + (35+y) = 180

but x = 49, so

49 + 77 + 35+y = 180

y = 19

AC=CB because its Radius

Answer:

Part A

The probability of the treatment groups mean being greater than the control group mean by 8points or more = (26+8+2)/1000 = 0.036

Part B

Yes, the result is statistically significant because the probability of the difference being 8point or more is less than 5% significant level

Part C

The answers is 0.036 means that there is a very little chance of obtaining difference of 8points or more by random chance. So, if the difference between treatment group mean and control group mean is at least 8 , then the result is significant which means protein shaken is actually helpful in speeding up the weight-10 process
