Answer:
The polynomial is 10x^2 + 10x -2
Step-by-step explanation:
To get the polynomial which represents the perimeter, what we need to do is to add up all
these values. We use the formula for finding the perimeter of a triangle and that involves adding up all the three sides. That would be;
2x^2 + 3x + 5x^2 -1 + 3x^2 + 7x -1
10x^2 + 3x -1 + 7x -1
10x^2 + 10x -2
If angle B measures 25°, the approximate perimeter of the triangle is 10.48 units. A right triangle is shown. Angle A is 90 degrees and angle B is 25 degrees.
it is a a rhombus......... parallelogram is also called as a rhombus....
