3 tan³ t(theta) = tan t(theta)
3 tan³ t - tan t = 0
tan t ( 3 tan² t - 1 ) = 0
tan t = 0
t 1 = k π , k ∈ Z
3 tan ² t - 1 = 0
3 tan ² t = 1
tan ² t = 1/3
tan t = +/- √3/3
t 2 = π / 6 + k π
t 3 = - π / 6 + k π , k ∈ Z
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that 
is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:
Knowing this, you can set up the following equation:
Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle .
This is:
I think it’s d. A percent is out of 100 so it’s 156/100
B.) 10 The length of the board is 7×12 = 84
the largest number of 15 inch pieces that
jeremy can cut is 5. 84÷15 is a quotient of
5 with a remainder of 9. 5×5=10
The answer is 7/4, 1 3/4 or 1.75
