Question

What’s the answer ??

Answer 1

`(√(11))/(6)`

Explanation:

Form a triangle in Quadrant 2 with a leg of length -5 and hypotenuse of length 6. Use the Pythagorean theorem to solve for the other leg, which turns out to be
`√(11)`. Finally use the definition of sine to solve the problem.

`\sin(\theta) = \sin(\cos^(-1)(-(5)/(6))) = (√(11))/(6)`
