I'm assuming you meant to write 8^(-2) or 
where the -2 is the exponent over the 8.
If my assumption is correct, then we use the rule 
So,
<h3>Answer: Choice D. 1/64</h3>
Thats means angle BEC is 63. By the vertical angle theorem AED is the same. 3x-27 when x=30 is also 63.
The numerical values of the circumference and area are equal.
The final answer is the same as given, which is cosecA= 2.....
hope it helped ☺️
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. The standard form of quadratic equation is ax2 + bx + c = 0. Upon substitution, we can easily determine the discriminant. If disc. is zero, the roots are equal; if <0, then the roots are positive and non-identical; if <0, the roots are negative and imaginary.
