Answer 2

To find the value of Y = sin(89 degrees), you can use a scientific calculator that has trigonometric functions or use trigonometric identities to simplify the calculation. However, please note that trigonometric functions typically take the angle in radians as input. Therefore, you need to convert 89 degrees to radians before finding the sine value.

Here's how you can do it:

Step 1: Convert 89 degrees to radians. 1 degree = π/180 radians So, 89 degrees = 89 * (π/180) radians

Step 2: Calculate sin(89 degrees) in radians. sin(89 degrees) = sin(89 * π/180) radians

Step 3: Use a calculator or lookup table to find the sine value. sin(89 degrees) ≈ 0.9998476952

So, the value of Y = sin(89 degrees) is approximately 0.9998476952.
