Answer:
36
Step-by-step explanation:
MC : BC : MB = 1 : √3 : 2
MC : BC = 1 : √3
12 : BC = 1 : √3
BC = 12 : 1/√3
BC = 12 × √3/1
BC = 12 × √3
BC = 12√3
MC : MB = 1 : 2
12 : MB = 1/2
MB = 12 : 1/2
MB = 12 × 2/1
MB = 12 × 2
MB = 24
AB = 2BD
AB = 2CD√3
AB = 2(½BC)√3
AB = 2(½ × 12√3) √3
AB = 2 × 6√3 × √3
AB = 12 × √9
AB = 12 × 3
AB = 36
