Question

Find the value of cos x° + sin yº ​

Answer 1

1.84

Explanation:

The given arc is a part of a unit circle centered at origin.

The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.

So, for angle equal to
`x`°, the x coordinate represents
`cos (x)`°.

So,
`cos x`° = 0.86

Similarly, the y-coordinate of angle y represent
`\sin y`°.

So,
`\sin y`° = 0.98

Therefore, the value of
`cos (x)`° +
`\sin y`° = 0.86 + 0.98 = 1.84.
