Question

Verify the following equalities: sin30° cos60°+ cos30° sin 60°= sin90​

Answer 1

Step-by-step explanation:

left hand side,

sin30° cos60°+ cos30° sin 60°

=1/2 ×1/2 + route3/2 + route 3/2

=1/4 + 3/4

=4/4

=1

right hand side,

sin90°= 1

Hence proved that left hand side = right hand side
