The vertex and sides of the angles are:

Lines: EF and FG; Angle: Angle F
Lines: GH and HI; Angle: Angle I

The angles are:

<B, <ABC, <CBA and ^B
<L, <KLM, <MLK and ^L

<h3>How to determine the angles and the vertices?</h3>

The measure of the angles

Here, there is no parameter to determine the measure of each angle.

This means that the measures of angles cannot be calculated; however, the angles can be classified.

The classification of the angles are:

Acute angle
Obtuse angle
Obtuse angle
Acute angle

The vertex and sides of the angles

The vertex is the point where two lines meet, while the sides are the lines

So, the vertex and sides of the angles are:

Lines: EF and FG; Angle: Angle F
Lines: GH and HI; Angle: Angle I

Name each angle in four way

The vertex is the point where two lines meet, while the sides are the lines

In this case, the angles are:

<B, <ABC, <CBA and ^B
<L, <KLM, <MLK and ^L

What is 2/5 plus 1/3

leva [86]

First, you need to get the denominators (the bottom number) the same. The smallest number to get them to is 15.

So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too. So you would get, 6/15.

Then, for 1/3, take the bottom number and multiply it by 5. Then, since you did it to the bottom, do it to the top as well. You would get 5/15.

Then, you need to put them side by side. You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.

 6 + 5 = 11
15 15 15

Compare the scores: a score of 75 on a test with a mean of 65 and a standard deviation of 8 and a score of 75 on a test with a m

LiRa [457]

Answer:

The Zscore for both test is the same

Step-by-step explanation:

Given that :

TEST 1:

score (x) = 75

Mean (m) = 65

Standard deviation (s) = 8

TEST 2:

score (x) = 75

Mean (m) = 70

Standard deviation (s) = 4

USING the relation to obtain the standardized score :

Zscore = (x - m) / s

TEST 1:

Zscore = (75 - 65) / 8

Zscore = 10/8

Zscore = 1.25

TEST 2:

Zscore = (75 - 70) / 4

Zscore = 5/4

Zscore = 1.25

The standardized score for both test is the same.

Explain how to subtract 247 from 538?

alexandr402 [8]

1. 538 - 247 = ?

2. 8 - 7 = 1

3. You can't subtract 3 and 4, so you have to take number from 5 (turning it into a 4) and then you add a 1 right next to 3 (which makes it 13;13 - 4 = 9

4. 4 - 2 = 2

538 - 247 = 291

So the answer is 291.

In another baseball division, one team had a winning percentage of 0.444 repeating What fraction of their games did this team wi

UkoKoshka [18]

Answer:

$x = \frac{4}{9}$

Step-by-step explanation:

Given

Winning Percentage = 0.444 repeating

Required

Represent as a fraction

Represent the percentage with x

$x = 0.444$

Convert to fraction

$x = \frac{444}{1000}$

Next step, is to convert to fraction repeating

To do this, we simply subtract 1 from the denominator

$x = \frac{444}{1000 - 1}$

$x = \frac{444}{999}$

Simplify to the lowest term: Divide numerator and denominator by 37

$x = \frac{444/37}{999/37}$

$x = \frac{12}{27}$

Simplify to the lowest term: Divide numerator and denominator by 3

$x = \frac{12/3}{27/3}$

$x = \frac{4}{9}$

Hence;

There winning fraction is $\frac{4}{9}$

How do i solve for this?

Firdavs [7]

9514 1404 393

Answer:

97.42 square units

Step-by-step explanation:

The area of a sector is given by ...

A = (1/2)r²θ

where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.

75° = (75°)×(π/180°) radians = (5/12)π radians

Then the area is ...

A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units

Equivalently, you can find the area of the circle in the usual way:

A = πr² = π(12.2²) ≈ 467.59465

Then, multiply by the fraction of the circle that is shaded (75°/360°)

sector area = (467.59465)(75/360) = 94.42 . . . square units
