Answer:
x = 11
Step-by-step explanation:
Based on the two secants intersecting theorem, thus, we have:
(x + 5)*5 = (38 + 2)2
5x + 25 = (40)2
5x + 25 = 80
5x = 80 - 25 (subtraction property of equality)
5x = 55
Divide both sides by 5
x = 11

The standard deviation of a binomial variable is
sqrt(n*P*(1-P))
where n is the sample size and P is the probability of one of the outcomes.
The sample size is 55 and we'll assume that both male and female are equally likely outcomes.
standard deviation = sqrt(55*.5*.5) = 3.7081%
44% is 1.6181 standard deviations away from the mean of 50%.
Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
First let us determine what <ABD is: 180º- 90º - 2nº = 90-2nº (the square represents a 90º angle
Then find <DCB: 180º - 90º - nº = 90-nº
Angle <ACB doesn't change: it is 90-n
but, <ABD is only part of <ABC: if we add <ABD with <DBC then we get 90-2n+n = 90-n
Definition of an isoceles triangle: It has two sides that are congruent or has two angles that are congruent.
Because both <ABC and <ACB equal 90-n the triangle ABC is an isoceles triangle.
Hope this Helps, and May the Force Be With You!
