Answer 1

Answer:

$tan A = cot B$

tan A = Tan ( 90-A)

tan A = tan 90 - tan A

tan A + tan A = tan 90

2tan A = Tan 90

tan A = tan 90/2

A = 90/2

A =45          -----1

tan A = cot B

cot ( 90 - B ) = cot B

cot 90 - cot B = cot B

Cot 90 = cot B + cot B

cot 90= 2cot B

cot 90/2 = cot B

90/2 = B

B =45           -----------2

TAKE 1+2

A + B = 45 + 45

A+B = 90
