Question

Sin60 cos30. +. Sin30 cos60

Answer 1

Answer:

1

Step-by-step explanation:

Sin60 .Cos30 +Sin30 .Cos60

√3/2 * √3/2 + 1/2 * 1/2

3/4 + 1/4

4/4 = 1

Therefore, Sin 60. Cos30 + Sin30 . Cos60 = 1

Answer 2

${\overbrace{\underbrace{\<strong><u>R</u></strong><strong><u>e</u></strong><strong><u>d</u></strong><strong><u>{Answer</u></strong>}}}}$.

➡Given here.

♠ Sin 60° Cos30° + Sin 30° Cos 60°

we know That:-

___________________

♠ SinX Cos Y + Sin Y Cos X = (Sin X + Y)

___________________

So,

♠ Sin 60° Cos 30° + Sin 30° Cos 60°

= Sin ( 60°+ 30° ).

= Sin 90°

= 1.

We know

_____________

♠ Sin 90° = 1.
