Question

If A and B are acute angles and sinA=cosB,then find the value of A+B​

Answer 1

Answer:

sin 45 =cos 45 then a +b =90

Answer 2

ok,

if they r acute angle, then their degrees will be below 90°

If sinA = CosB is acute angles then their Angles will be 45° .... (45° + 45° = 90°)

Therefore, Sin A = Cos B = 45°

A + B = 2 × 45° ....... (A = B )

A + B = 90°
