Answer:

The Commutative property is represented by 5 + (-8) = -8 + 5.

Step-by-step explanation:

We are the following the following expression below;

5 + (-8) = -8 + 5

  • Identity property;

This property says that is any number is added to 0, then the result is the number itself, i.e.;

2 + 0 = 2 or (-7) + 0 = -7.

  • Associative property;

Suppose there are three numbers; a, b and c.

So, this property hold the condition that; a + (b + c) = (a + b) + c

If we add the second and third numbers and then add the first number to it or if we add the first and second numbers and then add the third number to it, the result will be the same.

  • Commutative property;

Suppose there are two numbers 6 and 8.

This property states that if we add 6 + 8 or 8 + 6, both are equal, i,e;

6 + 8 = 8 + 6

14 = 14.

  • Distributive property;

This property states the following condition;

a \times (b + c) = (a \times b) + (a \times c)

So, 5 + (-8) = -8 + 5 is represented by the commutative property.

One angle of a triangle measures <img src="https://tex.z-dn.net/?f=10degrees" id="TexFormula1" title="10degrees" alt="10degrees"
iVinArrow [24]

Answer:

One\ angle: 35^o\\Second\ angle: 25^o\\Third\ angle: 120^o

Step-by-step explanation:

Let

x ----> the measure of one angle of the triangle

y ---> the measure of the second angle

z ----> the measure of the third angle

we know that

The sum of the measure of the interior angles in any triangle must be equal to 180 degrees

x+y+z=180^o -----> equation A

One angle of a triangle measures  10 degrees more than the second

x=y+10 ----> equation B

The measure of the third angle is twice the sum of the first two angles

z=2(x+y) ---> equation C

substitute equation B in equation C

z=2(y+10+y)

z=4y+20 ----> equation D

substitute equation D and equation B in equation A

(y+10)+y+(4y+20)=180^o

solve for y

6y=180-30\\6y=150\\y=25^o

Find the value of x

x=25+10=35^o

Find the value of z

z=4(25)+20=120^o

therefore

One\ angle: 35^o\\Second\ angle: 25^o\\Third\ angle: 120^o

Derek wants to construct a square box stall for each horse that is to be housed in a stable. He wants all of the box stalls to h
ale4655 [162]
The total area of the stable is 20,250 sq. ft.

Let n = total number of box stalls.

Each box stall is a square of length 9 ft.
Total area  = 9^2n = 81n ft².
Therefore
81n = 20250
n = 20250/81 = 250

Answer: 250 horses.

A sector with a central angle measure of \purpleD{175\degree}175°start color #7854ab, 175, degree, end color #7854ab has a radiu
Alisiya [41]

Answer: 219.94\ cm^2

Step-by-step explanation:

Given

The central angle of a sector measures 175^{\circ}

The radius of the circle is r=12\ cm

The area of the sector is given by

\Rightarrow A=\dfrac{\theta }{360^{\circ}}\pi r^2

Insert the values

\Rightarrow A=\dfrac{175^{\circ}}{360^{\circ}}\cdot \pi \times 12^2\\\\\Rightarrow A=219.94\ cm^2
