Answer:
9
Step-by-step explanation:
the only thing we can say for sure is that JL is splitting the triangle and also its baseline IK in half.
so, both sides of the baseline must be equal :
3x = x + 6
2x = 6
x = 3
=> LK = x + 6 = 3 + 6 = 9
V=lwh1/2
V=(24•20•30)1/2
V=17280•1/2
V=8,640
Hope this helps!
Answer would be B. Sorry if my handwriting is messy or if I didn’t explain enough
