Answer:
First question the answer is the third one, 4*4*4*4*4
Second: Part A
I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen to be 625 sqaure yards.
Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.
third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.
Can we get a picture or something?

Answer:
75
Step-by-step explanation:
A streight line has an angle of 180 so if you take 180 and subtract 105 you get 75
Answer:
See explanation below.
Step-by-step explanation:
A right triangle is a triangle that has a right angle (90º). In math, the Pythagorean theorem allows us to calculate the length of the sides of a right triangle.
In a right triangle, the legs are the two sides that meet at the 90º angle and the hypotenuse is the side that opposes the right angle. The Pythagorean Theorem tells us that the square of the hypotenuse equals the sum of the squares of the legs. In other words:
where c is the hypotenuse and a and b are the legs.
Now, we can use this formula to calculate the diagonal of the pool if we just have the length and the width (these would be the legs of the triangle). We need to measure both the length and the width and then square both of them and sum up the squares: this would give us the square of the diagonal so we will only need to find its quadratic root and we will have the length of the diagonal.
For example, let's say we have a pool that is 3 ft by 4ft, using the formula we have:
Therefore, in this case the diagonal would be 5 ft long.
