Answer:  The value of 'x' is 31.

Step-by-step explanation: As shown in the modified attached figure, AC and BD are two intersecting chords, where ∠CBD = x° and ∠CAD = 31°.

We are to find the value of 'x'.

The measures of the angles on the circumference of a circle subtended by the same chord (arc) are equal.

In the attached figure, ∠CBD and ∠CAD are angles subtended at the circumference of the circle by the same arc CD.

Therefore, we must have

\angle CBD=\angle CAD\\\\\Rightarrow x^\circ=31^\circ.

Therefore, the value of 'x' is 31.

Thus, (B) is the correct option.

PLEASEPLEASEPLEASE HELP!!!!!!!!!!! Don't mind to much of the notes, I think y=23, but what is x??
kirza4 [7]

REVISED

Answer:

x = 15.33

Step-by-step explanation:

3y is equal to 2x + 13. The reason why is because they are corresponding angles, (right next to each other). From there, you would have to substitute y into 3y. The equation should look like: 3(23) = 2x + 13. All that is left is to solve for x.

PLZ EXPLAIN. <br><br><br>what is the area of this figure?
BlackZzzverrR [31]

The area of this figure is 532m.

First you do the square which is 18 time 18 gets you 324m.

The for the first triangle you would do 18 times 16 then divide by 2 which is 144m.

For the last triangle you would do 16•8 div by 2 which will give you 64m.

Add them all up and you get 532m.

among a group of students 50 played cricket 50 played hockey and 40 played volleyball. 15 played both cricket and hockey 20 play
kondaur [170]

Answer:

Cricket only= 30

Volleyball only = 15

Hockey only = 25

Explanation:

Number of students that play cricket= n(C)

Number of students that play hockey= n(H)

Number of students that play volleyball = n(V)

From the question, we have that;

n(C) = 50, n(H) = 50, n(V) = 40

Number of students that play cricket and hockey= n(C∩H)

Number of students that play hockey and volleyball= n(H∩V)

Number of students that play cricket and volleyball = n(C∩V)

Number of students that play all three games= n(C∩H∩V)

From the question; we have,

n(C∩H) = 15

n(H∩V) = 20

n(C∩V) = 15

n(C∩H∩V) = 10

Therefore, number of students that play at least one game

n(CᴜHᴜV) = n(C) + n(H) + n(V) – n(C∩H) – n(H∩V) – n(C∩V) + n(C∩H∩V)

= 50 + 50 + 40 – 15 – 20 – 15 + 10

Thus, total number of students n(U)= 100.

Note;n(U)= the universal set

Let a = number of people who played cricket and volleyball only.

Let b = number of people who played cricket and hockey only.

Let c = number of people who played hockey and volleyball only.

Let d = number of people who played all three games.

This implies that,

d = n (CnHnV) = 10

n(CnV) = a + d = 15

n(CnH) = b + d = 15

n(HnV) = c + d = 20

Hence,

a = 15 – 10 = 5

b = 15 – 10 = 5

c = 20 – 10 = 10

Therefore;

For number of students that play cricket only;

n(C) – [a + b + d] = 50 – (5 + 5 + 10) = 30

For number of students that play hockey only

n(H) – [b + c + d] = 50 – ( 5 + 10 + 10) = 25

For number of students that play volleyball only

n(V) – [a + c + d] = 40 – (10 + 5 + 10) = 15
