How to find the value of x? BEST ANSWER WILL BE PICKED!?

Could you please help me find the value of x in congruent triangles? So, could anyone help explain how to find the value of x in triangle JGE if side JG is 32. Side BD is 24 and side AD is 40 in triangle ABD. How do I find the value of x in triangle JGE? Could someone explain to me in simple 8th grade terms? BTW, x is on side EG!!!
