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 °, 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.
