Question

Which of the following is the exact value of sin 495°?

Answer 1

Given the following question:

Exact value of sin(495):

Remove 360 of the current 495 since they're full rotations.

495 - 360 = 135

135 ÷ 3 = 45

Now find the exact value of sin(45):

`\sin (45)=0.70710678=\frac{\sqrt[]{2}}{2}`

Which means your answer is option A.
