Answer 1

$\red{☆ \: Answer :}$

• $BC \: = \: 4 \sqrt{5}$

$\red{☆ \: Explanation :}$

Given That :

• Side AB = 8 cm
• Side AC = 4 cm

To Find :

• Side BC?

Solution :

• Two sides AB & AC are given.

• For fnding third side we use Pythagoras Theorem.

By Pythagoras Theorem,

BC² = AB² + AC²

⟹ BC² = 8² + 4²

⟹ BC² = 64 + 16

⟹ BC² = 80

⟹ BC = $4 \sqrt{5}$

$\red{☆ \: Let's \: \: Verify :}$

By putting the value of Side BC,

⟹ (BC)² = (AB)² + (AC)²

⟹ $(4\sqrt{5})^{2}$ = 8² + 4²

⟹ 16 × 5 = 64 + 16

⟹ 80 = 80

⟹ LHS = RHS

Hence Verified.
