Given the triangle below, which of the following is a correct statement?

EleoNora [17]

ANSWER

(A)csc angle C equals 3 over 2

EXPLANATION

The cosecant is hypotenuse over opposite.

$\csc(C) = \frac{6}{4}$

$\csc(C) = \frac{3}{2}$

$\csc(B) = \frac{6}{5}$

The secant is the hypotenuse over adjacent.

$\sec(C)=\frac{6}{5}$

$\sec(B) = \frac{6}{4}$

$\sec(B) = \frac{3}{2}$

The only correct choice is A
