if tan a + b is equal to 1 and 10 a minus b is equal to one upon under root 3 so zero degree greater than a + b and greater than 90° so A is greater than B then find the values of a and b

tan a+b =1 ,tan 1 =45degree ..now ,a+b =45
tan 10 a-b =1/under root3 ,tan 1/under root 3 =30degree ...now 10 a -b =30 on subtracting both these equation we get a=6.81 and b =38.19 now a/c to question zero is greater than a+b that is , 0<(6.81+38.19)and we get 0<45 ..and next part less than 90..45<90 ...
