Find the value of cos x° + sin yº

1.84

Step-by-step 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 °, the x coordinate represents °.

So, ° = 0.86

Similarly, the y-coordinate of angle y represent °.

So, ° = 0.98

Therefore, the value of ° + ° = 0.86 + 0.98 = 1.84.
