Question

if tan A=cot(A_18) ,where 2A is an acuteangle,find the value of A​

Answer 1

Step-by-step explanation:

tan 2A = cot(A -18°)

cot(90 -2A) =cot (A -18°)

comparing angles

90 -2A = A -18

90 +18 = A +2A

108 = 3A

108/3 =A

36 = A

A = 36°

Answer 2

Answer:A=54

Step-by-step explanation:

So,tan A= cot(A-18)

=>cot(90-A)=cot(A-18)

=>90-A=A-18

=>108=2A

=>54=A
