AB = 115

AC = 43

∪BC = 360 — (AB + AC) = 360 — (115 + 43) = 202

<BAC = ∪BC / 2 = 202/2 = 101

6 + 4 = 10

360 : 10 = 36

6 * 36 = 216

4 * 36 = 144

AaB = 144

AbB = 216

∪AMB = 360 — ∪AaB = 360 — 140 = 220

6 + 5 = 11

220 : 11 = 20

5 * 20 = 100

<BAM = ∪BM : 2 = 100 : 2 = 50

AO = OB

AB² = AO² + OB² = 2AB²

576 = 2AO²

AO² = 576 : 2 = 288

AO = √288 = √144 * 2 = 12√2

OM² = AO² — AM² = 288 — 144 = 144

OM = √144 = 12
