Answer:
Arc length s = 15.3 inches
Step-by-step explanation:
We know that length of an arc that subtends an angle θ radians at the center is given by
where
r is the radius of the circle
θ is the angle subtended in radians
Thus applying values we get
thus s = 15.3 inches
Answer:
A
Step-by-step explanation:
We want to solve the equation:
To do so, we can rewrite the equation.
Recall the double-angle for sine:
By substitution:
Distribute:
We can subtract 3cos(x) from both sides:
And factor:
Hence, our answer is A.
*It is important to note that we should not divide both sides by cos(x) to acquire 10sin(x) = 3. This is because we need to find the values of x, and one or more may result in cos(x) = 0, and we cannot divide by 0. Hence, we should subtract and then factor.
