Question

if A is an acute angle of a ABC, right angle at B, then the value of sinA+cosA is ;

Answer 1

Sin A + Cos A  would be greater than 1

Bcoz.....

If u substitute any acute angle the ans would go more than 1

For Example Let A = 30°

sin 30° + cos 30° = 1/2 + √3/2

                            = √3 + 1 / 2

                            = 1.732 + 1 / 2   = 2.732 / 2  = 1.366 >1

Answer 2

Answer:

Sin A + Cos A  would be greater than 1

Step-by-step explanation:

If you substitute any acute angle the answer would go more than 1.

Assuming,

Let A = 30°

Therefore, Sin 30° + Cos 30°

                  = 1/2 + √3/2

                  = √3 + 1 / 2

                   = 1.732 + 1 / 2  

                  = 2.732 / 2  

                  = 1.366 > 1 (Greater than 1)
