Question

of a is an acute angle on right triangleABC right
angled at B, then the value of SinA + CosA
​

Answer 1

Answer:

Correct option is

B

greater than one

△ABC is a right angled triangle and right angle at B

sinA=

AC

BC

, cosA=

AC

AB

⟹sinA+cosA=

AC

BC

+

AC

AB

=

AC

BC+AB

[We know that sum of two sides of a triangle is greater than the third side]

⟹sinA+cosA>

AC

AC

=1

Hence, sinA+cosA>1
