Question

if cos Q= 1 by root 2 then Q is equal to??​

Answer 1

$\LARGE \underline{ \bf \blue{ Solution}} :$

$\large\tt\implies\cos \theta = \dfrac{1}{ \sqrt{2} } \\ \\ \large\tt\implies\cos \theta = \cos45 \degree \\ \\ \large\tt\implies\theta = 45 \degree$

Answer 2

Answer:

Cos Ø =1/√2

Cos 45°= 1/√2

→Ø=45°
