Answer and Explanation:
Given : Sides of right triangle 5,12 and 13.
To find : Show that the area of a right triangle of sides 5, 12 and 13 cannot be a square ?
Solution :
If 5,12 and 13 are sides of a right angle triangle then
13 is the hypotenuse as it is largest side.
then we take perpendicular as 12 and base as 5.
The area of the right angle triangle is

Here, h=12 and b=5



The area of the right angle triangle is 30 units.
30 is not a perfect square as 
There is no square pair formed.
Answer: It a vertical line.
Step-by-step explanation:
Answer: B. 11/13
Step-by-step explanation:
So he starts out with 16, and picks out 3 of those 13. This means that he now has 13 socks in total in the drawer, so therefore, the answer could only be A or B. However, what makes it B, is that if he doesn't put them back, the only way he wouldn't get a full pair is with the green pair. That is where the 11/13 comes in, as two of the socks are green, making it not a full pair. But since he has 3 more black socks, 5 more white socks, and 3 more grey socks, when you add those together you get 11
5+3+3=11

Answer:
Follows are the solution to this question:
Step-by-step explanation:
In point A:
The two-point C and y is given, where C is the scale drawing lengths and y is the actual mural lengths so, the formed equation is:

In point C
:
Using the value of the scale:
let 1 feet: 20 feet
therefore the equation is:

The size of c will be the length of:

The diagram c scale width will be:
