Cosecant of C = hypotenuse/ opposite side
hypotenuse =√ (-8)² + (-6)² = √100 = 10
Cosecant of C = 10/ -8 = - 5/4
Correct option A
Answer:
-84 + 10i
Step-by-step explanation:
first, you want to take out the negative symbol from the square root, and we know that i = sqrt(-1) (sqrt = square root)
so the equation would look like
i x sqrt(100) - 84
solve for the square root of 100 which is 10
now the equation is
10i - 84
that is the answer and you can flip the equations so it can look like the actual answer
-84 + 10i
