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:

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. <em>y </em>is the square root of 237.62. √237.62 = 15.41492783… So we can tell x = 45º and y = 15.41492783…

Hope this helps! Plz give me brainliest, it will help me achieve my next rank.

Answer:

81 cubic feet of wood

Step-by-step explanation:

Divide it into 5 sections, each 3 feet long because it is 15 feet long.

(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =

9 + 18 + 27 + 18 + 9 = 81

Which function represents the graph of f(x)=|2x| after it is translated 5 units to the left?
Mashutka [201]
As you need to translate to the left this is an horizontal translation so you have to replace f(x) by f(x-h) and when h is less than 0 the graph shifts left, it mean h is negative. So for this problem g(x)= Ι2(x--5)Ι  then g(x) = Ι2(x+5)Ι
