Question

if tan 7A = cot (A-6°) whare 7A is acute angle then find A​

Answer 1

Answer:

tan7A = cot(A-6)

cot(π/2 -7A) = cot(A-6°)

90-7A = A -6

A = 96/8 = 12

Answer 2

Answer:

tan 7A= cot (A-6°)

= tan7A = tan{90°-(A-6°)}

= 7A = 90°-A+6°

= 7A= -A+96°

= 7A+A= 96°

= 8A= 96°

A= 96°/8

A= 12°

the value of A= 12°
