Can you use a calculator? If yes, then isolate 7) cot 8) tan 2 theta, etc. Then, input the inverse of that trig into the calculator.
Ex. #7 cot theta= -6/5
Then, input arccot (-6/5) (aka inverse cot (-6/5)) into your calculator.
Answer:
(5x + 1)x(2x^2+1)
Step-by-step explanation:
using the Pythagorean Thereom:
3^2 +4^2 = X^2
9 +16 = 25
x^2 = 25
X = sqrt (25)
x = 5
it would be 5 miles
