Question

if a(1, 3), b(1, 3), c(2, 5) and d(x, 5) are the vertices of a parallelogram abcd, then the value of x is

Answer 1

Answer:

X = 2

Step-by-step explanation:

mid point of ac = mid point of be

$( \frac{1 + 2}{2} \: \: \: \: \: \: \: \: \: \frac{3 + 5}{2} ) = ( \frac{x + 1}{2} \: \: \: \: \: \: \: \: \frac{5 + 3}{2} ) \\ \\ x + 1 = 3 \: \: \: \: \: \: \: \: \: \: \\ \\ x = 2.$
