Answer:
18492-2516
Elevation: 15976
Step-by-step explanation:
Since the climber descended 2516 feet, we can write 18492-2516.
Pythagoreon theorem
a^2+b^2=c^2
5^2+10^2=125 not 20^2
Coterminal angles are angles that end in the same position on a unit circle.
We can find angles that are coterminal to -4pi/3 by adding and subtracting 2pi.
-4pi/3 + 2pi = 2pi/3
The answer is 2pi/3
