If the perpendicular AD divides the base of the Δ ABC such that BD, CD and AD are in ratio 2 : 3 : 6, then angle A is equal to -
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
From Δ ADB, tan θ 1 = 
= 
or θ 1 = tan –1 
= tan –1 
……..(1)
and from Δ ADC, tan θ 2 = 
= 
or θ 2 = tan –1 
= tan –1 
……..(2)
∠ A = θ 1 + θ 2
∠ A = tan –1 
+ tan –1 
= tan –1 
= tan –1 (1) =
