Answer:
x = 3
Step-by-step explanation:
We are told that the length of a side of the square is x.
Now, perimeter of square = 4 × side length
Perimeter of square = 4x
Also,we are told that the triangle is equilateral and a side is (x + 1).
Thus, perimeter of triangle = 3(x + 1)
Since we are told that the perimeter of the square is equal to that of the equilateral triangle. Thus;
4x = 3(x + 1)
4x = 3x + 3
Subtract 3x from both sides to get;
4x - 3x = 3
x = 3
I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
When I do what the problem statement says, I get 47° for the left angle and 58° for the right one. They are not congruent.

Answer:
15
Step-by-step explanation:
the answer should be 15 because, if one cup is 120 calories or 8 fluid ounces is 120 calories, divide 120 by 8 so you can find how many calories one fluid ounce is.
