I got SET 1.

The question was correct.

Tan(A+B) =1

Tan(A-B) =1/,√3

This is the correct question.

A = 37.5°

B = 7.5°

Plz mark my ans as the brainliest.

For any more queries you can ping me.

Anonymous: You didn't need to divide

Anonymous: You just had to substitute 1 =tan45° and 1/√3 = tan 30°

Anonymous: On equating you get A+B=45

Anonymous: A-B=30

Anonymous: Yeah most probably as the CBSE States that a number in fractions or roots should be converted into decimal number
