Which out of the 2 choices is correct ?

tiny-mole [99]

Answer:

sinB is correct

Step-by-step explanation:

Calculating each of cos/ sin for ∠B

cosB = $\frac{adjacent}{hypotenuse}$ = $\frac{6}{3\sqrt{5} }$ = $\frac{2}{\sqrt{5} }$ and

$\frac{2}{\sqrt{5} }$ × $\frac{\sqrt{5} }{\sqrt{5} }$ = $\frac{2\sqrt{5} }{5}$ ≠ $\frac{\sqrt{5} }{5}$

--------------------------------------------------------------------------------

sinB = $\frac{opposite}{hypotenuse}$ = $\frac{3}{3\sqrt{5} }$ = $\frac{1}{\sqrt{5} }$ and

$\frac{1}{\sqrt{5} }$ × $\frac{\sqrt{5} }{\sqrt{5} }$ = $\frac{\sqrt{5} }{5}$

Answer:

$\frac{x {y}^{ - 1} }{2 {x}^{0}{y}^{ - 2} } \\ = \frac{x {y}^{2} }{2 \times 1 \times y} \\ = \frac{x {y}^{2} }{2y} \\ = \frac{xy}{2}$

<h3>(xy)/2 is the right answer.</h3>
