Question

(ANSWER PLEASE) Let (sin x)(cos x) = .35 and sin x + cos x = 1.30. Which is (csc x) + (sec x)?
A. 3.71
B. 2.17
C. 3.77
D. 2.71

Answer 1

3.71

Answer 2

\[\frac{sinx}{0.35}=\frac{1}{cosx}=sec x\]
\[\frac{cos x}{0.35}=\frac{1}{sinx}=csx x\]
plus them together to get the answer, that's it

Answer 3

think of it this way

\[\csc(x) + \sec(x) = \frac{1}{\sin(x)} + \frac{1}{\cos(x)} = \frac{\sin(x) + \cos(x)}{\sin(x)\cos(x)}\]

then its numeric substitution
