Question

If tan a + b is equal to 1 a minus b is find a and b

Answer 1

Answer : a=45 and b=0

Step-by-step explanation:

Tan (a+b)=1   ........[a]

Also,

Tan45=1   .......[b]

From [a] and [b],we get

(a+b)=45   .........[c]

Then,

(a-b)=45 .........[d]                    { [a-b] taken as 0 since not mentioned in question}

Adding eqn [c] and [d],we get

2a=90

a=45

putting a=45 in ....[c] ,we get

b=0
