Question

if angle a and angle b are acute angles such that tan a=tan b then prove that angle a= angle b​

Answer 1

hey mate

answer:

if tan a =tan b

then,

we know that tan theta =cot(90-theta)

cot (90-a) = cot (90-b)

cot will be cancelled

90-a=90-b

90 n - are also cancelled

the required result is a= b
