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 ,
- Value of base = 1
- Value of hypotenuse = √2
On substituting the respective values ,
For rationalizing the denominator , multiply numerator and denominator by √2 , we have,
Simplify ,
1/4
if 3/4 cyclists finish then that leaves 1/4 of the group that did not finish
The y intercept is - 1
It is where the line touches or crosses the y axis
