Question

if tan (a + b) = 1 and cos (a - b) = root 3 by 2 find a and b​fastest answer would be marked as brainliest

Answer 1

Answer:

Tan(a+b) = root3tan(a-b)= 1/root3We know tan 60 = root 3 and tan 30 ... OF A AND B FASTEST WILL BE MARKED AS BRAINLIEST . 2. See answers.

Answer 2

Answer:

that's an easy question !

Step-by-step explanation:

tan (a+b)=1 (given)

tan45°=1

a+b=45(first eq)

cos(a-b)= √3/2 (given)

cos30°= √3/2

a-b=30 (second eq)

by subtracting eq2 from eq1 -

2b=15

b=15/2

by adding this value in first eq

a+b=45

a+(15/2)=45

a=75/2

a= 75/2

b=15/2

hope it will help
