Which classification describes AMNO with vertices M(2, -3), N(3, 1), and<br> 0(-3, 1)?
Sonja [21]

Answer:

Option D

Step-by-step explanation:

32). Given vertices of the triangle are M(2, -3), N(3, 1) and O(-3. 1).

Distance between two points (x_1,y_1) and (x_2,y_2) is given by the expression,

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance between M(2, -3) and N(3, 1) will be,

MN = \sqrt{(3-2)^2+(1+3)^2}

      = \sqrt{1+16}

      = \sqrt{17}

Distance between M(2, -3) and O(-3, 1),

MO = \sqrt{(2+3)^2+(-3-1)^2}

      = \sqrt{25+16}

      = \sqrt{41}

Distance between N(3, 1) and O(-3, 1),

NO = \sqrt{(3+3)^2+(1-1)^2}

      = 6

Condition for right triangle,

c² = a² + b² [Here c is the longest side of the triangle]

By this property,

MO² = MN² + NO²

(\sqrt{41})^2=(\sqrt{17})^2+6^2

41 = 17 + 36

41 = 51

False.

Therefore, given triangle is not a right triangle.

Since, length of all sides are not equal, given triangle will be a scalene triangle.

Option D is the correct option.

What operations have inverse relationship
Sergio [31]
The operation that reverses the effect of another operation. 

Example:
Addition & Subtraction are Inverse Operations.


Start with 7, then add 3 we get 10, now subtract 3, and we get back to 7.


Another:
Example: Multiplication & Division are inverse operations. 

Start with 6, multiply by 2, we get 12, now divide by 2, and we get back to 6.




Hope this helps!!!!!!!

morpeh [17]

Step-by-step explanation:

\sqrt{1/8}=\sqrt{1} /\sqrt{8}

\sqrt{8} =2\sqrt{2}

1/(2\sqrt{2} )

if the denominator is a root then multiply itself by itself to get an integer

1(2\sqrt{2} )/((2\sqrt{2})(2\sqrt{2} ))

\sqrt{2} /4

Hope that helps :)
