If PQ=7 and QR=10,

P=(7/Q) and R=(10/Q)

Therefore:

PR=(7/Q)(10/Q)

=(70)/Q²

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show your work.

LuckyWell [14K]

Step-by-step explanation:

Quadrilateral ABCD is inscribed in a circle.

Opposite angles of a Quadrilateral are Supplementary.

$\therefore \: \angle A + \angle C = 180° \\ \therefore \:(2x + 3) \degree+ (2x + 1) \degree = 180° \\ \therefore \: (4x + 4) \degree = 180° \\ \therefore \: (4x + 4) = 180 \\ \therefore \: 4x = 180 - 4 \\ \therefore \: 4x = 176 \\ \therefore \: x = \frac{176}{4} \\ \therefore \: x = 44 \\ \\ m\angle A = (2x + 3) \degree \\ = (2 \times 44 + 3) \degree \\ = (88 + 3) \degree \\ \huge \red{ \boxed{ \therefore \: m\angle A =91 \degree}} \\ \\ m\angle C = (2x + 1) \degree \\ = (2 \times 44 + 1) \degree \\ = (88 + 1) \degree \\ \huge \red{ \boxed{ \therefore \: m\angle C=89\degree}} \\ \\ m\angle D= (x - 10) \degree \\ = (44 - 10) \degree \\ \huge \red{ \boxed{ \therefore \: m\angle D =34\degree}} \\ \\ similarly \\ \\ \huge \red{ \boxed{ \therefore \: m\angle B = 146\degree}} \\ \\$

There are 60 students in a class. Among them,20 students are girls .Find the ratio ofa. Boys and total studentsb. girls and tota

valina [46]

Answer:

Girls to boys = 1:2

Girls to students = 1:3

Boys to students = 2:3

Step-by-step explanation:

So, let's subtract the number of girls from the number of students in the class:

60 - 20 = 40

This means that for every 20 girls there are 40 boys in the ratio of girls to boys:

20:40

This can be simplified down by factoring, here we can divide by 20:

(20 ÷ 20) : (40 ÷ 20)

1:2

So the ratio of girls to boys is 1:2

The ratio of boys to students can be calculated via:

40:60

This can be simplified by dividing by 20 again:

(40 ÷ 20) : (60 ÷ 20)

2:3

So the ratio of boys to students is 2:3

The ratio of girls to students can be put in a ratio of:

20 : 60

This can be simplified down by dividing by 20:

(20 ÷ 20) : (60 ÷ 20)

1:3

So the ratio of girls to students is 1:3

Hope this helps!
