Question

cos60° cos 30° +sin45° sin30°​

Answer 1

Step-by-step explanation:

Sin 45°=1/√2

Cos45°=1/√2

sin30°=1/2

Cos30°=√3/2

Therefore

=Sin45°×cos30°+cos45°×sin30°

=1\√2 × √3\2 + 1\√2 × 1\2

=√3\2√2 + 1\2√2

=√3 +1\2√2

Therefore answer is √3+1\2√2

Answer 2

Answer:

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