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

Choose the list that shows these numbers in order from smallest to largest.
svetlana [45]

Answer:

0.3, 0.32, 0.321, 0.345

Step-by-step explanation:

The maximum number of decimals shown in the series is 3.

Therefore, let's rewrite all the numbers with three decimal places.

0.32, 0.321, 0.3, 0.345 can be written as

0.320, 0.321, 0.300, 0.345

Now, we can easily compare the numbers and we can conclude:

0.300 < 0.320 < 0.321 < 0.345

Hence, the smallest to largest order is:

0.3, 0.32, 0.321, 0.345

Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, a
beks73 [17]

Answer:

<D = 100

<E =30

<F =50

Step-by-step explanation

Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e

<A = <D

<B = <E

<C = <F

Given

<A = 100 then <D = 100

<B = 30°, then <E = 30°

To get <F, we will use the expression

<D+<E+<F = 180 (sum of angles in a triangle is 180°)

100+30+<F = 180

130+<F = 180

<F = 180-130

<F = 50°

Hence the measure of <F is 50°
