Question

if tan A =0.25 and A+B =90degree find cot B​

Answer 1

Answer:

0.25+B=90

Step-by-step explanation:

B=90-0.25

B=89.75

Answer 2

Given :-

tanA = 0.25 = 25/100 = 1/4 (convert decimal into fraction)

A + B = 90°

Solution :-

tanA = 1/4 ......eq(1)

A + B = 90°

B = 90° - A

so,

cot B = cot ( 90° - A )

cot B = tanA........( from eq(1))

therefore, the value of

cot B = 1/4 or 0.25
