Answer:
sin(∅) = -√65/65
Step-by-step explanation:
The identities that relate the cotangent, the cosecant, and the sine are ...
csc² = 1 +cot²
sin = 1/csc
_____
For the given values, we find ...
csc(∅)² = 1 +cot(∅)² = 1 +8² = 65
csc(∅) = -√65 . . . . . . . . . . . . . . . . square root with attention to sign
sin(∅) = -1/√65 = (-√65)/65

Answer:
-5 and 3
Step-by-step explanation:
The roots of a quadratic function are also called the x intercepts.
The x intercepts are found by looking where where the quadratic equation crosses the x, or horizontal axis.
In this case, the quadratic equation crosses the x axis at (-5,0) and (3,0).
Therefore, our roots are -5 and 3
