Suppose that p is the point on the unit circle obtained by rotating the initial ray counterclockwise through 240°. find the measure of the reference angle for 240°, and then find sin(240°) and cos(240°).

Reference angle will be 60°

sin(240°)

cos(240) =

Step-by-step explanation:

We have given angle 240°

We ave t find the reference angle of 240°

As we know that 240° will lie in third quadrant

And for third quadrant reference angle is given by

Reference angle = angle - 180° =240°-180 = 60°

Now we have to find the value of sin(240°)

Now

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer:

your answer is: c. 196 7/8 in^3.
