Answer:

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 [tex]x[/tex]°, the x coordinate represents [tex]cos (x)[/tex]°.

So, [tex]cos x[/tex]° = 0.86

Similarly, the y-coordinate of angle y represent [tex]\sin y[/tex]°.

So, [tex]\sin y[/tex]° = 0.98

Therefore, the value of [tex]cos (x)[/tex]° + [tex]\sin y[/tex]° = 0.86 + 0.98 = 1.84.
