Answer:
4
Step-by-step explanation:
Sin(30) = LJ/8sqrt(3)
Sin 30 = ½
LJ = 4sqrt(2)
LM = JM = x
x² + x² = (4sqrt(2))²
2x² = 32
x² = 16
x = 4
14:20 and 21:30 or 28:40
1530cm
First figure (9x10)x9=810
Second figure (18x10)x4=720
720+810=1530
it could be -50.35 and 50.35 since the absolute value is just the positive value of the number
28/2
