Question

Hey! Can someone please help me? I'm a bit lost. (Answer and explanation please!)

Find the value of j and the measure of each diagonal.

Answer 1

j=11, AC=50, DB=38

Explanation:

I suppose the ABCD is a parallelogram.

by the property of parallelogram ,the diagonals bisect each other.

4j-19 = 2j+3

2j = 22

j = 11

AC = (4j-19) + (2j+3) = 50

BD = 2 * (2j-3) = 38
