Answer:
?=9
Step-by-step explanation:
We have a special right triangle, the 45-45-90 triangle.
In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.
Since we know that the side length is 9, this means that:
The ? is 9.
The given equation is non-linear.
Solution:
Given expression is .
To find the equation is linear or non-linear.
Linear equation is a straight line which is in the form ax + by + c = 0.
Otherwise it is non-linear equation.
⇒
Do cross multiply for the fractions to make the denominators same.
⇒
⇒
Do cross multiplication.
⇒
⇒
Here, there is no constant term.
So, the equation is not a straight line.
Hence, the given equation is non-linear.
