Question

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

A. cot angle B= 6/5
B. csc angle C= 3/4
C. cot angle C= 8/5
D. csc angle B= 4/3

Answer 1

In order to answer this question we need to know what csc and cos mean/
csc A = 1/ sin A = 1 / opposite cathetus/ hypotenuse = hypotenuse/opposite cathetus
cot A = cos A/sin A = adjoining cathetus / hypotenuse/ opposite cathetus/ hypotenuse = adjoining cathetus/ opposite cathetus

cot B= 5/6
csc B = 8/6 = 4/3
cot C = 6/5
csc C = 8/5

As we can see the right option is D.
