Question

help me pleaseeee Find x and y.

Answer 1

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.

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

Answer 2

Answer:

x = 45º and y = 15.414927836…

Step-by-step explanation:

To find xº, we can tell that every angle of the square is 90º. If xº is ½ of one of those angles, x = 90 ÷2 = 45º. We can find y by using the Pythagorean Theorem, which consists of the formula a² + b² = c². 10.9² + 10.9² = 237.62. y is the square root of 237.62. √237.62 = 15.41492783… So we can tell x = 45º and y = 15.41492783…
