The length of the sides of any right triangle are always less than the length of the hypotenuse. The sine and cosine functions find the ratio between a side and the hypotenuse, so it's always less than 1.
Answer:
b. Kathy
Step-by-step explanation:
We compare each of their score by how far away from the mean when in term of the standard deviation. Using the following formula

For John he is (85 - 75)/5 = 2.
For Kathy she is (80 - 50)/10 = 3.
Since Kathy is 3 standard deviation better than her class' average, while John is only 2's. We conclude that Kathy did better.
Answer:
1. 11.8x9.8=115.64 115.64/2=57.82 (57.82Inches)
2. 12x5=60 60/2=30 (30m)
3. 25x9=225 9x9=81 81/2=40.5 225-40.5=184.5 184.5/92.25 (92.25ft)
