Answer:
D. tan(-π/6)
Step-by-step explanation:
The tangent function is periodic with a period of π, so ...
tan(5π/6) = tan(5π/6 ± kπ) . . . for any integer k
For k = -1, we have ...
tan(5π/6) = tan(5π/6 -π) = tan(-π/6)
3.1 is like a example when it is hiding a zero behind it and you find this when you do a math problem and you don't put zero in front of a number like 100-89 you don't write "011" so that is why it is like that
Answer:
6/5
Step-by-step explanation:
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
=
+ ![/adj2/^{2}](https://tex.z-dn.net/?f=%2Fadj2%2F%5E%7B2%7D)
=
+ ![/13/^{2}](https://tex.z-dn.net/?f=%2F13%2F%5E%7B2%7D)
576 =
+ 169
= 576 - 169
= 407
x = ![\sqrt{407}](https://tex.z-dn.net/?f=%5Csqrt%7B407%7D)
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
