Answer:
B
Step-by-step explanation:
3p+6p+6p=180°
15p=180
p=12
3p=12×3=36°
6p=12×6=72°
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.
Answer:
open circle
Step-by-step explanation:
the open circle does not include the number. this is what you want because the solution is not equal to the number
Set up a proportion.
3/6 = 5.5 / x Cross multiply
3x = 6*5.5
3x = 33 Divide by 3
x = 33/3
x = 11
The length of x is 11.
