Answer:
D. 264°
Step-by-step explanation:
When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs. Therefore, 
60° = 1/2[(18x - 6)° - (5x +17)°]
60° * 2 = (18x - 6 - 5x - 17)°
120° = (13x - 23)°
120 = 13x - 23
120 + 23 = 13x 
143 = 13x 
143/13 = x 
11 = x 
x = 11
(18x - 6)° = (18*11-6)°= (198 - 6)° = 192°
(5x +17)° = (5*11 +17)° =(55+17)° = 72°
m (arc KNL) = (18x - 6)° + (5x +17)° = 192° + 72° 
m (arc KNL) = 264°
 
        
             
        
        
        
Answer:
-A+B
Step-by-step explanation:
if what you mean is what a negative expression would be as a+b the answer would be negative A+B
 
        
             
        
        
        
A number cube is rolled 120 times. The number 4 comes up 47 times. 
We have to determine the experimental probability of rolling a 4.
The formula to evaluate probability of an event is given by:
 Probability  = 
So, Probability of rolling a 4 = 
= 
Now, we have to find the theoretical probability of rolling a 4.
Total number of outcomes of number cube = {1,2,3,4,5,6}
Probability of rolling a 4 = 
So, Option B is the correct answer.
