Question

Find x if cos (10degree +x)=1\2

Answer 1

Answer:

(10 degree +x) 1\2

Step-by-step explanation:

X=10degree -1\2=9\2

Answer 2

$\underline{ \underline{\bf{Answer}}} : - \\ \boxed{x = 50} \degree \\ \\ \underline{ \underline{\bf{ step - by - step \: explanation}}} : - \\ \\ \: \underline{ \bf{ to \: find }:} - \\ find \: the \: value \: of \: x \: \\ \\ \underline{\underline{ \bf{solution}}} : -$

According to the question:-

$\implies \: \cos(10 + x) = \frac{1}{2} \\ \because \: \cos(60 \degree) = \frac{1}{2} \\ \therefore \\ \\ \implies \: \cos(10 + x) \degree = \cos(60 \degree) \\ \\ \implies \: 10 + x = 60 \\ \\ \implies \: x = 60 - 10 \\ \\ \implies \: \boxed{ x = 50 \degree}$
