Any quadrilateral which can be inscribed in a circle, is called a cyclic quadrilateral.


The main theorem about these quadrilaterals is the following:

In any cyclic quadrilateral, the sum of the measures of the opposite angles is 180°.

This means, m(∠S)+m(∠Q) =180°, 

thus 

(7x-2)+(5x+14)=180

12x+12=180

12x=168

x=168/12=14

Thus the measures of angles Q and S are respectively:

7x-2 = 7*14-2=96 (degrees) and 

5x+14=5*14+14=6*14=84 (degrees)

Answer: D

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 16 years; the
STatiana [176]

Using the Emperical rule:

68% lie with one one standard deviation:

16 + 1.7 , 16-1.7 = 17.7, 14.3

14.3 is part of the 68%.

The remaining 32% of the distribution is outside the range, with half being less than and half being greater than.

32/2 = 16

The probability of living loner than 14.3 Would be 16%

AlexFokin [52]
These two events are complimentary. So P(not rain)=1-P(will rain)
So, 75% is my guess
