Help me pleaseeee Find x and y.

Alex777 [14]

Answer:

x = 45°

y = 15.41 units

Step-by-step explanation:

Given quadrilateral is a square. Each angle of square is 90°

Diagonal of square bisects the angle.

$\therefore \: x = \frac{90 \degree}{2} = 45 \degree \\ \\ \because \: diagonal \: of \: square \: is \: \sqrt{2} \: times \: the \: \\ side \: of \: square \\ \therefore \: y = \sqrt{2} \times 10.9 \\ \therefore \: y = 1.414 \times 10.9 \\ \therefore \: y = 15.4126 \\ \therefore \: y \approx \: 15.41 \: units$
