Answer:
(I don't know if this is correct)
To find the length of the rectangle, you need to first do 20 x 2 = 40 because when you finding the perimeter you have to do W + L + W + L = P (or Wx2 + Lx2 = P). You then subtract 40 from 68 (68 - 40) where you get 28 left. you then just divide 28/2 and you get 14. I may be way off but that's how I learned it.
I can see why you need help. I don't quite understand what the question is, but both options are factually correct
It is an irrational number.
As a decimal, it equals 1.414235... This is a nonrepeating and nonterminating decimal, which makes it an irrational number, It also cannot be represented as a ratio of two integers.
Answer:
The corner angles are 80° (JKL) and 100° (MJK), while the side lengths are 261
Step-by-step explanation:
Because the specified length measures are rhombus diagonals, each side will be the hypotenuse of a triangle with legs half as long:
(122 + 102) = 244 = 261 15.62... side length
The stated angle measure is half that of J. Because the whole measure of J is 100°, the full measure of K is 180° -100° = 80°.
