Answer 1

$\bold{\huge{\fbox{\color{Maroon}{Answer}}}}$

sin60 cos 30 + sin30 cos60

= √3/2 x √3/2 + 1/2 x 1/2

= 3/4 + 1/4 = 4/4 = 1

We can also say that sin 60º.cos 30° + sin 30º.cos 60°= tan45°

Hope this helps u.

Answer 2

Answer:

sin60°=√3/2

cos60°=1/2

sin30°=1/2

cos30°=√3/2

√3/2×√3/2+1/2×1/2

=3/4+1/4

=4/4

= 1 ans...
