Answer:
Step-by-step explanation:
A right angled ∆ is given to us and we need to find out the value of cos 45° ( with rationalized denominator ) . As we know that in a right angle ∆ , the value of cosine is ,
In the given triangle ,
On substituting the respective values ,
For rationalizing the denominator , multiply numerator and denominator by √2 , we have,
Simplify ,
Using the <u>arrangements and the probability concept</u>, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.
In this problem, there are 4 elements, hence .
A number is a multiple of 4 if the <u>number composed by it's last 2 digits are multiples of 4</u>.
The other 18 numbers formed are not divisible by 4, hence:
0.75 = 75% probability that the number formed is not divisible by 4.

Hello!
There are three possible lengths.
We need to keep in mind that the total area cant exceed , so, knowing that, we just need to find numbers that can be multiplied giving as result 60.
