Question

Find the value of
Sin² 60°+cos²45°

Answer 1

Answer:

sin 60 = $\sqrt{3}$/2

cos 45 = $\sqrt{2}$/2

=sin²60+cos²45

=(root 3/2)² + (root2/2)²

=3/4+2/4

=5/4

here's your answer

Answer 2

$\tt \:\frac{5}{4}$

Step-by-step explanation:

To find :-

• Value of Sin² 60°+cos²45°

SolutioN:-

✤ sin 60° = √3/2

✤ cos 45° = 1/√2

Put the values in Sin² 60°+cos²45°

$\implies \tt \: {[\frac{√3}{2}]}^2\: +\:{[\frac{1}{√2}]}^2$

$\implies \tt \:\frac{3}{4}\: +\:\frac{1}{2}$

$\implies \tt \:\frac{3 + 2}{4}$

$\implies \tt \:\frac{5}{4}$

Therefore,

Sin² 60°+cos²45° $\implies \tt \:\frac{5}{4}$
