Tan 2A = Cot ( A - 18) where 2A is an acute angle find the value of A

1.	Tan 2A = Cot ( A - 18) where 2A is an acute angle find the value of A
Answer» Cot ( 90 - 2A) = cot A -1890-2A = A- 18 3 A =108 A = 36 Tan 2A= tan (90-(A-18)).....2A=90-A+18.....3A=108...A=108/3=36....ans Tan(90-2A)=Cot (A-18).......90-2A=A-18........90+18=A+2A........108=3A........A=108/3.......A=36 36
