Question

solve the answer below.
cos²45+sin30

Answer 1

cos²45 = (1/√2)² = 1/4

sin30 = 1/2

cos²45 + sin30 = 1/4 + 1/2 = 3/4

Answer 2

here is ur answer:

${ \cos }^{2} 45 + \sin(30) \\ \\ {( \frac{1}{ \sqrt{2} }) }^{2} + \frac{1}{2} \\ \\ \frac{1}{2} + \frac{1}{2} \\ \\ \frac{2}{2} \\ \\ 1$

hope it helps you!
