Question

In triangle abc ab = 6√3 cm , ac= 12cm find bc angle a = 90°

Answer 1

GivEn:-

• AB = 6√3cm

• AC = 12cm

• ∠A = 90°

To find:-

• BC = ?

SoluTion:-

∆ABC is right angled triangle because ∠A = 90°

Therefore,

★ Using Pythagoras Theorem :-

→ (AC)² = (AB)² + (BC)²

→ (12)² = (6√3)² + BC²

→ 144 = 108 + BC²

→ 144 - 108 = BC²

→ 36 = BC²

★ Taking sqrt. both sides :-

→ √36 = √(BC)²

→ 6 = BC

Hence, BC = 6cm
