Question

If tan a minus b is equal to 1 by root 3 and tan a + b is equal to 23 find a and b

Answer 1

ur question has a fault it's not 23 its root3

here is ur answer bacha

----------------------------------------

tan a-b= 1/root3

tan a-b = tan 30°

a-b= 30 (1)

tan a+b = root3

tana+b = tan60°

a+b= 60° (2)

add 1 &2

a-b= 30

a+b= 60

= 2a = 90

a= 45

a+b= 60

45+b = 60

b = 60 -45

b = 15
