Question

If A,B are acute angles such that sinA=cos B, then S+B= ​

Answer 1

Answer:

given SinA= CosB

Sin45= Cos45= 1/2

A=45, B= 45

A+B = 45+45

= 90 degree

Answer 2

Step-by-step explanation:

Given that:-

A,B are acute angles such that sinA=cos B,

=>SinA=Sin(90-B)

we know that CosA=Sin(90-A)

=>A=90-B

=>A+B=90°

=>A+B=180°/2

=>A+B=π/2

A,B are complementary angles
