Question

Sin 30° × Cos 30° + Sin 45° × Cos 45° = ?​

Answer 1

Answer:

√3+2/4

Step-by-step explanation:

=sin30°×cos30°+sin45°×cos 45°

=(1/2×√3/2)+(1/√2×1/√2)

=√3/4+1/2

=(√3+2)/4

Answer 2

Answer:

(√3+1)/4

Step-by-step explanation:

Sin30° = 1/2

cos30° = √3/2

sin45° = cos45 = 1/√2

$\frac{1}{2} \times \frac{ \sqrt{3} }{2} + \frac{1}{ \sqrt{2} } \times \frac{1}{ \sqrt{2} }$

$\frac{ \sqrt{3} }{4} + \frac{1}{2}$

$\frac{ \sqrt{3} + 2}{4}$
