Answer:
We know that since it's a square, the lenght size is the same on all sides. We can simply use pythagoras theorem:
a^2 + a^2 = 13.5^2
13.5^2 = 182,25
182,25 : 2 (because there are 2 'a') = 91,125
<u>The square root of 91,125 is 9,55 feet.</u>
Answer:
I believe its 12%
Step-by-step explanation:
60-48=12 so 12%
Answer:
12
Step-by-step explanation:
Writing the equation, we get
2x - 9 = x + 3
2x -x = 9+3
x = 12.
The sum of the measures of the angles in a triangle is always 180 degrees.
If you follow the procedure in the question, you will have a straight angle when you put the pieces together. All straight angles have 180 degrees. Therefore, there are 180 degrees in every triangle.
I, ii and iii as same length sides
