Pythagoras theorem.... The thing I hate the most..
In a traingle if you know two if its sides ( we say A and B ) you square them and get the third side C .
You didn't understand.
Let me explain.
We have a triangle, one side is 4cm other is 3cm how do you find the third side?
Yes, Pythagoras theorem.
That is a^2 + b^2 = c^2.
You square 4 and 3:
That will be 16 and 9 then you add them.
16+9= 25 find the root of 25 that is 5.
You get the third side as 5cm.
That's how you use Pythagoras theorem.
Answer:
x = 14
Step-by-step explanation:
If the perimeter is 80, then that is (x+6) + (x+6) + (x+6) + (x+6). If you want to find x, you have to get rid of 6. 6+6+6+6 = 24. The perimeter, 80, minus 56. You then divide 56 by 4 to get x. That is 14. To check, you find (14+6)*4. That is 80.

Answer:
41 square miles
Step-by-step explanation:
There are several ways you can compute the area of this polygon. We have elected to divide it into a rectangle and a triangle.
The rectangle has dimensions 8 × 4.5, so area ...
A = LW = 8 × 4.5 = 36 . . . . . square miles
The triangle has height 2.5 and base 4, so area ...
A = (1/2)bh = (1/2)(4)(2.5) = 5 . . . . . square miles
Then the total area is the sum of these:
36 + 5 = 41 . . . . . square miles
