A=h(b+c)
A/h=b+c
b=(A/h)-c
Answer: b=(A/h)-c
1= 22.08
2= 25704
3= 587
4= 610
Plug the 5 into the x in the equation 2x. it should be 2(5) which equals 10.
Since the figure is a rhombus, the diagonals cut each other at right-angles and bisect each other, namely cut their vertices in equal halves.
what the dickens does all that mean? well, the angles at vertex C and vertex A are all twins, and therefore, ∡BCA = x, therefore
2 x 3 = 6
55 + 6 = 61
It's probably a 2-step problem
