Question

plz plz sol it sol 3rd que​

Answer 1

Answer:

A = 36

Step-by-step explanation:

tan 2A = cot(A - 18)

cot(90 - 2A) = cot(A - 18) (cot are cancel on both side)

90 - 2A = A - 18

90 + 18 = A + 2A

108 = 3A

108/3 = A

36 = A

Answer 2

Hi there !!

tan2A =cot(A-18°) ( tanA= cot(90-A)

cot(90°-2A ) = cot(A-18°)

90-2A = A-18

90+18 = A+2A

108= 3A

A=36°

Thankyou :)
