Answer:
x = 4.2
Step-by-step explanation:
14.1² + x² = 14.7²
198.81 + x² = 216.09
216.09 - 198.81 = 17.28
√17.28 = 4.15
x = 4.15
Round to nearest tenth
x = 4.2

There's no equation. You must've forgotten to put the file in the question.
Hey I would try to use Photomath or Socratic they are both apps that are downloadable
Answer:
4m, 4m, and 5 m
Step-by-step explanation:
From the information give;
- Two sides of a triangle are equal in length
- The third side is 3 m less than the common length
- Perimeter of the rectangle is 13 m
We are required to determine the dimensions of the triangle;
- Assuming the common sides are x m each
- Then, the third side will be (2x-3) m
- Perimeter of a triangle is equal to the sum of the lengths of the three sides
Therefore;
(2x-3) + x + x = 13 m
4x - 3 = 13m
4x = 16 m
x = 4 m
and, 2x-3 = 5 m
Therefore, the lengths of the three sides of the triangle are 4m, 4m, and 5 m
