Question

Diagonals of parallelograms

Solve for x

Answer 1

Answer: 10

Assuming the parallelogram is general and congruent:

`2x + 10 = 3x \\ 3x - 2x = 10 \\ x = 10`

Answer 2

Diagonals bisect each other

`\\ \bull\tt\longmapsto 2x+10=3x`

`\\ \bull\tt\longmapsto 3x-2x=10`

`\\ \bull\tt\longmapsto x=10`

Option B
