D
cos A
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, c)
Referring to Δ AHB (see fig.), we have
= 
⇒ AH = 
= 
= 2 R cos A 
So that is correct while is not correct. Also,
AH = 2R cos A = 2 . 
cos A = 
cos A
and AH = 2R cos A = 
. cos A = a cot A
So that is correct, while is not correct.
