Answer:
Suzanne is incorrect.
Step-by-step explanation:
To figure out if the two equations are equivalent, we can simplify each one of them.
Simplifying the first equation, we get:
Simplifying the second equation, we get:
Now that both equations are simplified, we can see that the equations are not equivalent. Suzanne is incorrect.
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 ,
