Heya !
Using a theoram about triangles ,
Given a triangle ∆ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side ,
Also , the length of third side always greater than absolute difference of the other two sides ,
Let the third side be x ,
So , x < 9 + 8 and x > 9 - 8
x < 17 and x > 1
Hence , x ∈ [ 2 , 17 ] inch.
Above case is true for any triangle , be it scalene , Isosceles , Right-angled ...
As , for Isosceles , the third side can be 8 or 9 inches ,
For scalene , all values in the above range satusfies ,
For right angled triangle , we have 2 cases ,
Case 1 : Third side is the hypotenuse
Then , x = √(9²+8²) = √145 = 12.0415 inch.
Case 2 : Third side is not the hypotenuse
Then , x = √(9²-8²) = √17 = 4.1231 inch.
Hope it helps you ! :)
The area of a triangle formal is base times height divided by 2. So 9x 12 which equals 108 then you divide that by 2 which equals 54 and the unit is cm^2
Answer:
Therefore the False statements are,
∅ N is an Empty set Which is False Statement.
{0} N is False Statement. because Natural number does not contain zero.
Step-by-step explanation:
Natural Number:
- A natural number is an integer greater than 0.
- Natural numbers begin at 1 and increment to infinity: 1, 2, 3, 4, 5, etc.
- Natural numbers are also called "counting numbers" because they are used for counting.
- N = { 1 , 2 , 3 , 4 , 5 , ............. }
Therefore,
∅ N is an Empty set Which is<u> False Statement.</u>
<u>{</u>0} N is<u> False Statement.</u> because Natural number does not contain zero.
{1} N is True because one is Natural number.
This is your answer and for the multiplication I gave it to you step by step
