Question

if you use acute angle of a triangle ABC, right angled at B, then the value of Sin A + cos A is; options
a1
b>1
c2
d<1

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
