Question

find the value of sin30degree ×cos 45degree+sin45degree×cos 30 degree​

Answer 1

Answer:

sin30°cos45°+sin45°cos30°

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

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

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