Given :-
∠B = 90°
∠C = ∠A = 45°
AB = 6 cm
To find :-
Length of AC = ?
Solution:-
Let side AC be x.
We know that side opposite to equal angle is equal.
So,
⟹ ∠C = ∠A
⟹ AB = BC
⟹ BC = 6 cm ( because AB is also 6 cm.)
So, by Pythagoras Theorem which is applied on the Triangle ABC which is Right Angled Triangle :-
⟹ AC² =BC² +AB²
⟹ AC² = (6)² + (6)²
⟹ (AC)² = 36 + 36
⟹ AC² = 72
⟹ AC = √72
⟹ AC = 8.48 cm
So, length of AC is 8.48 cm.
