Question

cos²45⁰+sin²30⁰find the value
​

Answer 1

Answer:

0.75

Step-by-step explanation:

We know cos 45=1/√2 and sin 30=1/2

Therefore cos²45 will be (1/√2)² which is 1/2 and cos²30 will be (1/2)² which is 1/4

Add em and you get (1/2)+(1/4)

Take 4 as LCM and you'll get it as (2+1)/4

Calculate it and boom u get 0.75
