Answer:
please post a more cohesive question. The values are very confusing
a=180-142=38 degree
b= 180-38-88=54 degree
c=b (since the two lines are parallel to each other) therefore c=54 degree
I think this is Pythagoras' theorem you are asking for
a^2+b^2=c^2
87^2+387^2=157338
Square root of 157338 = slope = 396.6585
396.66 ft
The answer is A because I'm smart I make straight a so yea its A
Answer: A.
Step-by-step explanation: First you must think about how many miles is 9 kilometers. How many miles in 9 kilometers is 5.59234. And A is the closest to the numbers of miles Tristan rode his bike. The other questions would be wrong. It isn't the exact one because it's the closest, not exact. Hope that helps :).
