In triangle ABC, ∠ BAC = 75°, ∠ABC = 45°.BC is produced to D. If ∠ ACD = x°, then x/3 % of 60° is

1. 30°
2. 48°
3. 15°
4. 24°

Correct Option: D

As per the given in question , we draw a figure of a triangle ABC

Given that , ∠ BAC = 75°, ∠ABC = 45° , ∠ ACD = x°
As we know that sum of three angles of triangle is 180°
∠ ACB = 180° – 75° – 45° = 60°
∠ ACD = 180° – 60° = 120° = x

∴	x	% of 60°	= 60 ×	120	= 24°
