Step-by-step explanation:
I gave you the answer earlier too!
for more info !
<h2>there s a theorem called MIDPOINT THEOREM </h2>
Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points
<h2>so AB=1/2of YZ</h2>
which means
2x-4 = 1/2×21
thus, 2(2x-4) =21
=> 4x-8 = 21
4x = 29
<h2>x= 29/4 = 7.25</h2>
Thank youuuuuuuuuuuuuuuuuu
