Question

Prove that sin 30degree cos60degree+cos 30degree sin 60degree=1.

Answer 1

SOLUTION ☺️

=)L.H.S

=) sin 30° cos 60° + cos30° sin 60°

$= > \frac{1}{2} \times \frac{1}{2} + \frac{ \sqrt{3} }{2} \times \frac{ \sqrt{3} }{2} \\ \\ = > \frac{1}{4} + \frac{3}{4} \\ \\ = > \frac{4}{4} = 1$

Answer 2

Step-by-step explanation:

Cos30=√3/2sin60=√3/2sin30=1/2cos60=1/2therefore cos30+sin60/1+sin60+cos60=cos30therefore√3/2+√3/2/1+1/2+1/2=√3/2 2√3/2/1+1=√3/2 √3/2=√3/2

therefore proved
