Answer:
Here, we will use the formula from trigonometry which defines a radian
we know that an angle is a radian when the length of the radius of the circle is equal to the length of the arc formed
hence, if the radius is r and the arc is r, the angle (in radians) will be 1
if the radius is r and the arc is 2r, the angle in radians will be equal to:
length of arc / radius = 2r/r = 2 radians
I believe this will explain what is actually happening in these type of questions
So, the equation:
Θ(in radians) = s / r (where the length of arc is s and the radius is r)
π/4 = s / 12
s = 3π or 9.42 inches
Answer:
Step-by-step explanation:
<u>Given:</u>
If g(x) is the inverse of f(x), find it.
<u>Swap x with g(x) and f(x) with x:</u>
<u>Solve for g(x):</u>
X = 6 / tan(67)
x = 2.546
rounded to nearest tenth x = 2.5
Answer: -5x
Step-by-step explanation: combine like terms hope this helps!
