Please heĺp me

Answer 1

Step-by-step explanation:

Since, diagonals of a square are perpendicular bisector of each other, hence 13x +5.5° should be equal to 90°

$\therefore \: 13x + 5.5 \degree = 90 \degree \\ \therefore \: 13x = 90 \degree - 5.5 \degree \\ \therefore \: 13x = 84.5 \degree \\ \therefore \: x = \frac{84.5 \degree }{13} \\ \implies \: \huge \fbox{x =6.5\degree}$
