18. 105=2x-11 so 105+105=210 and all four angels equal 360 so 360-210=150 so 150/2=75
19. 6x+19+x =180
X=23
So AEB:75 BEC:123 CED:75 AED:23

This is the formula of finding the hypotenuse: a² + b² = c².
So the legs would be a and b.
4² + 4² = c²
c² = 16 + 16
c² = 32
c = √32 (Option C)
This formula only applies if the track is circular. If it is, then we write the equation:
2*r*pi=400
Dividing by 2pi, we see that:
r=200/pi
This is approximately 63.66.
Summing all the ingredients to get the total sample size, we applied the formula for obtaining the probability which is
Pr(3) = 0.5
<h3>Probability</h3>
Given Data
Sample Space
Total Sample size = 6
Probability of identifying 3 ingredient used is
Pr(3) = 3/6
Pr(3) = 1/2
Hence the Probability is 0.5
