answer for 11th question ​

Answer 1

❥${\underline{\underline{\huge{\mathtt{Question:-}}}}}$

If $cos\theta=\frac{1}{\sqrt2}$ ,then find the value of 4+cot∅.

❥${\underline{\underline{\huge{\mathtt{Solution:-}}}}}$

cos∅ = 1/√2

→ cos∅ = cos45°[cos45° = 1/√2]

→ ∅ = 45°

Now,

4+cot∅

→4 + cot45°

→4 + 1 [ cot45°=1]

→ 5 ( Answer)

Answer 2

$\huge \mathfrak{Answer:-}$

$\implies$ 5

$\huge \mathfrak{Solutions:-}$

$\implies$ cos(theta) = 1/√2

$\implies$ cos(theta) = 45° [cos 45° = 1/√2]

$\implies$ (theta) = 45°

Now,

$\implies$ 4 + cot(theta)

$\implies$ 4 + cot 45°

$\implies$ 4 + 1 [cot 45° = 1]

$\implies$ 5
