Question

find sin 30° + cos 60°​

Answer 1

Answer:

1 is the ans

Step-by-step explanation:

sin30 value is 1/2

& cos 60 value is 1/2

so,

sin 30 +cos 60

=1/2+1/2

=1+1/2

=2/2

=1

Answer 2

Answer:

1

Step-by-step explanation:

Method 1

sin 30° = 1/2

cos 60 = 1/2

1/2 + 1/2 = 1

Method 2

cos x = sin(90-x)........ Trigonometric Identity

cos 60° = sin (90-60)°

= sin 30°

sin 30° = 1/2

sin 30° + cos 60° = sin 30° + sin 30°

= 1/2+1/2=1
