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
°, the x coordinate represents  °.
°.
So,  ° = 0.86
° = 0.86
Similarly, the y-coordinate of angle y represent  °.
°.
So,  ° = 0.98
° = 0.98
Therefore, the value of  ° +
° +  ° = 0.86 + 0.98 = 1.84.
° = 0.86 + 0.98 = 1.84.
