Answer 1

Answer:

sorry I didn't get a chance to slove this problem

Answer 2

Answer:

Step-by-step explanation:

We have:

tan(A)=cot(B) tanA×tanB = 1 {cot B =1/tan A}

since

tan(A+B) = (tan A + tan B)/(1-tanA

× tanB)

tan(A+B)=(tanA+tanB)/(1-1)

tan(A+B)=not defined

A+B=pi/2 [tan(pi/2)=not

defined]
