Question

28. The value of sin 60° cos 30° + sin 30° cos 60° is:
(a)0
(b)1
(c)2
(d)4​

Answer 1

☞Question.

$\sf\green{sin60°cos30° + sin30° cos60° = ?}$

☞Solution.

→$\sf\green{ sin60° = √3/2 }$

→$\sf\green{ cos30°=. √3/2}$

→$\sf\green{ sin30° = 1/2}$

→$\sf\green{ cos60° = 1/2}$

☞then,

➝ $\sf\green{sin60°cos30° + sin30° cos60° }$

➝$\sf\green{ √3/2 × √3/2 + 1/2 × 1/ 2 }$

➝$\sf\green{ 1 + 1 = 2}$

$\huge\sf\underline{\underline{\red{AnsWeR}}}$

→ $\sf\green{ option ( c )}$
