Question

The value of (sin 30 degrees + cos 30 degrees) - (sin 60 degrees + cos 60 degrees) is

Answer 1

Answer:

sin 30=1/2

cos 30=√3/2

sin60=√3/2

cos60=1/2

according to the question,

(1/2+√3/2)-(√3/2+1/2)

(√3+1/2)-(√3+1/2)=0

Hope this helps!

Answer 2

(sin30°+cos30°)-(Sin60°+cos60°)

=sin30°+cos30°-cos30-cos60)

=sin30°-cos60°)

=0.5-.05

=0
