Simplify the expression. quantity cosecant of x to the power of two times secant of x to the power of two divided by quantity secant of x to the power of two plus cosecant of x to the power of two. a. sin^2x b. cos^2x c. -1 d. 1

D. 1

Step-by-step explanation:

We have the expression,

We get, eliminating the cosecant function,

As, sinx is reciprocal of cosecx and cosx is reciprocal of secx,

i.e.

i.e.

Since, we know that,

Thus,

So, after simplifying, we get that the result is 1.

Hence, option D is correct.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
