Answer:
a=45°and b=15°
Step-by-step explanation:
tan (a+b) =√3
tan(a+b) = tan60°
a+b=60°......(1)
cot(a-b) = √3
cot(a-b) = cot30°
a-b =30°.......(2)
add equation (1) and (2) we get
a=45° and b=15°

Given
- Tan (A+B) =√3
- cot(A-B)=√3
To find
- angle a and angle b
Solution
we are provided with equations of tan and cot respectively and our asked to find the angles,
we know that tan 60 = √3
therefore, tan 60 = tan (A+B)
or, 60 = A+B
in a similar manner,
cot[A-B] = √3
or, 1/tan(A-B) = √3
or, tan(A-B) = 1/√3
= tan30
or, A-B = 30
solving both of the equations we get,
A= 45° and B = 15°
Therefore, the angle A is 45 degree and b is 15 degree
