Question

how to find a rhombus other diagonal if a side and one of the diagonals are given

example
side=6
one of the diagonal =20​

Answer 1

Answer:

Step-by-step explanation:

Draw a rhombus and its diagonals. You’ll get  4  right triangles, with hypotenuse being one side of rhombus, and the legs being half of each diagonal:

(d12)2+(d22)2=s2  

d214+d224=s2  

d21+d22=4s2  

d22=4s2−d21  

d2=4s2−d21−−−−−−−−√
