Question

number 3 in solve u son ​

Answer 1

Answer:

TAN(A+B)=√3                        TAN(A-B)=1/√3

⇒TAN(A+B)=TAN60              TAN(A-B)=30

⇒A+B=60 (1)                           ⇒A-B=30

                                               ⇒A=30+B (2)

IN EQ 1,

A+B=60

30+B+B=60  (FROM EQ 2)

2B=30

B=15

IN EQ 2, A=30+B= 30+15= 45

Step-by-step explanation:

Answer 2

Answer:

tan(A+B)=60..............1

tan(A-B)=30................2

by elimination.........

2A=90

A=45..

put the value of A in equation 1...

(A+B)=90

45+B=90

B=90....

please make it the brainlist answer ....please i need your help......
