What is the difference between an inscribed angle and a central angle?

Answers

Answer/Step-by-step explanation:

An inscribed angle is an angle that is formed by two chords in a circle. The vertex of an inscribed angle is at any point on the circumference of the circle.

On the other hand, a central angle is an angle that is formed by two radii of a circle. The vertex of a central angle is at the centerbof a circle.

Thus, from the diagram attached below, <EFG is an inscribed angle while <EOG is the central angle of the circle O.

Inscribed angle = ½ of the central angle.

The length of a rectangle is 3 inches longer than twice its width, where w is the width of th
rectangle. The area of the rectangle is 90 square inches. *

Answers

Answer:

6 in and 15 in

Step-by-step explanation:

Given:

l = 2w + 3A = 90 in²w = ?l = ?

Area formula:

A = lw

Substitute values and solve for w:

(2w+3)w = 902w² + 3w = 902w² + 3w - 90 = 0w = (-3 ± [tex]\sqrt{3^2 - 4*2*(-90)}[/tex])/2*2w = (-3 ± √729)/4w = (-3 ± 27)/4w = 6 (positive root only)

The width is 6 in, find the length:

l = 2*6 + 3 = 15 in

width be x

Length be 2x+3

Now

area=Length×Breadthx(2x+3)=902x²+3x=902x²+3x-90=0

On solving we will get

x=6[Take positive]

Now

Length=2(6)=3=15in

A teacher is making worksheets for the next unit. He can create 3 worksheets in an hour and has 10 worksheets already created from the previous year. Which of the following lengths of time worked will not be long enough for the teacher to have created 27 worksheets. * Check All That Are True*
6 hours, 10 hours, 8 hours, 2 hours, 4 hours

Answers

Answer:

2 hours, 4 hours

Step-by-step explanation:

So lets go over what we know.

There are already 10 worksheets created.

Every 1 hour 3 more are made.

27 worksheets need to be made.

Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:

27-10

Now, lets divide the amount of worksheets we still need, by how many we make each hour:

17/3

Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.

Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.

Hope this helps! ;)

What is the value of x?
Enter your answer in the box.

Answers

Answer:

183

Step-by-step explanation:

982

Answer:

Step-by-step explanation:

You can use the degrees to find the answer. A right triangle always adds up to 180 degrees. The right angle is 90 degrees.

X + Angle A + Angle B = 180 degrees.

Substitute.

X + 90 degrees + 45 degrees = 180 degrees.

Add them up.

x + 135 degrees = 180 degrees.

now subtract 135 from both sides.

x = 45

In the following diagram, medians AD and BE intersect at F. Which of the following segments would not be true

1) ECD~ACB
2) EF= 1/2EB
3) ED||AB
4) the median drawn from C would pass through F

Answers

Answer is number 1 you welcome

The segment that is false is (2) EF= 1/2EB

The median lines of a triangle always meet at a point.

This means that the line from point C is true (option 4 is true)

The median divides the side lengths of the triangle into equal segments.

However, the centroid at point F do not divide line EB into equal segments

This means that:

[tex]A=\frac{1}{2}*40*27-\pi *6^{2}[/tex]

→ [tex]540-113.04[/tex]

Formula

V = 1/3 * B * H

Givens

B = 6*6

H = 4

Total = 108 + 48 = 156

The entrance hall in Black's family house has a perimeter of 71 2/3 ft.IF it is 9 2/5 ft wide, how long is it?

Answers

Answer: 26 13/30 feet

Step-by-step explanation:

The hall is in the shape of a rectangle. The perimeter of a rectangle is:

= 2(length + width)

= 2l + 2w

Since perimeter = 71 2/3 ft and Width = 9 2/5 ft wide, the length will be calculated thus:

Perimeter = 2l + 2w

71⅔ = 2l + 2(9 2/5)

71 2/3 = 2l + (2 × 47/5)

71 2/3 = 2l + 94/5

71 2/3 = 2l + 18 4/5

Collect like terms

2l = 71 2/3 - 18 4/5

2l = 71 10/15 - 18 12/15

2l = 52 13/15

l = (52 13/15 ÷ 2)

l = 793/15 × 1/2

l = 793/30

l = 26 13/30

Therefore, the length is 26 13/30ft
