ST is a midsegment, which tells you that BD=2(ST) or ST=½BD. Use that to substitute the values and find ST.
BD=2(ST)
29+x=2(2x+31)
29+x=4x+62
29=3x+62
-33=3x
x=-11
Now that we know x, we can substitute that into 2x+31 to find ST
ST=2x+31
ST=2(-11)+31
ST=-22+31
ST=9
Answer:
x = 3
Step-by-step explanation:
8x - 12 = 4x
<em>subtract 4 from each side</em>
4x - 12 = 0
<em>add 12 to each side</em>
4x = 12
<em>divide each side by 4</em>
x = 3
