Just a couple of rules are needed to solve this.
a) When secants cross inside a circle, the measure of the angle where they cross is the average of the measures of the intercepted arcs.
b) When secants meet outside the circle, the measure of the angle where they meet is half the difference of the measures of the intercepted arcs.
c) As a corollary to the first rule, if the secants meet on the circle, the angle where they meet is half that of the intercepted arc (because the other angle in the averge is zero).
Step-by-step explanation:
12/18=2/3
2/3×100%=66.67%
12/24=1/2
1/2×100%=50%
12/30=2/5
2/5×100%=40%
12/48=1/4
1/4×100%=25%
Answer:
I am not entirely sure what you are asking here but if I am right then the answer is -4(x-2) = 8 - 4x
Step-by-step explanation:
Multiplying binomials all you have to do is distribute the 4
Multiply -4 by x to get: -4x
Muliply -4 by -2 to get: 8 (Because two negatives make a positive)
Now you have -4x + 8
Rewrite so it flows better and the answer is:
8 - 4x
Answer:

Step-by-step explanation:
From the question we are told that
Angle 
Height of plane 
Generally the equation for the total distance flown is mathematically given by


Therefore total distance flown is
