Rule:

the side opposite the right angle) is equal to the sum of the squares of the other two sides. This is shown as A squared + B squared = C squared and is known as the 3-4-5 rule in construction.

Step-by-step explanation:

the answer is 45 i just did it on oddesy ware

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
