Answer:
x and y = 5√2.
Step-by-step explanation:
This is a 45:45:90 triangle so length of x = length of y.
In this triangle the ratio of the sides is 1:1:√2
Finding length of x and y:
1/√2 = x/10
√2x = 10
x = 10/√2
= 10√2/2
= 5√2.
The expression simplifies to x/y, so the answer is no, it is not a polynomial. The fact that a variable is in the denominator means it's not a polynomial.
