now, we could check for the CA distance, however, we already know that AB ≠ BC, so there's no need.
Answer: The unit circle contains values for sine, cosine, and tangent.
Step-by-step explanation: The coordinates on the unit circle are the sine ratio and cosine ratio. From this, the tangent, secant, cosecant, and cotangent can be found.
Answer:
Step-by-step explanation:
First we subtract 18.95 from 50 to get 31.05. Then we divide our new number by .15 to get 207 which is your number of miles :)
Answer:
85.5
Step-by-step explanation:
57 + 57/2 = 57 + 28.5 = 85.5
