Hi there!
For any 45 45 90 right triangle, the length of the hypotenuse is always the square root of 2 times one of the legs.
To get the lengths of the leg, let's divide the length of the hypotenuse by the square root of 2.
We get the following:
When simplifying fractions like this, we want to avoid having radicals on the bottom. In order to remove the radical from the denominator, let's multiply the numerator and the denominator by the square root of 2.
We get the following:
That's your answer.
Have an awesome day! :)

Answer:
Graph the equation is shown below.
Step-by-step explanation:
The linear equation representing the relation between cost of ordering a pizza and the number of additional toppings is:
Here,
<em>y </em>= cost of the pizza
<em>x</em> = number of toppings
The graph of the linear equation is shown below.
Consider the point (2, 10.25).
When <em>x</em> = 2 compute the value of <em>y</em> as follows:
The point (2, 10.25) satisfies the equation.
Again consider a point (18, 18.25).
When <em>x</em> = 18 compute the value of <em>y</em> as follows:
The point (18, 18.25) satisfies the equation.
The two points are also plotted on the graph.
