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:
False
Step-by-step explanation:
1/3^4=3^4
0.012346≠81
False
$2.00=100%-25%=75%
50%=$1.00
so that means 75% =$ 1.50
Answer:
2.5, √5, 5/3, √9/4
Step-by-step explanation:
√5 = 2.236
5/3 = 1.667
√9/4 = 0.75
Answer:
-18/7
Step-by-step explanation:
When subtracting a negative, the sign becomes positive, so now the equation would be -3 2/7 + 5/7.
By turning -3 2/7 into an improper fraction, you would get -23/7 + 5/7.
-23 +5 = -18 so -18 would be the numerator over the denominator (7) equals -18/7
