Given square ABCD, with point P on side AB , point Q on side BC, point R on side CD, and point S on side DA as shown. Additional

ly, P is 2/3 of the way from A to B, Q is 2/3 of the way from B to C, R is 2/3 of the way from C to D, and S is 2/3 of the way from D to A. Compute the ratio of the area of square PQRS to the area of square ABCD. Write your answer as a fraction in lowest terms.

The ratio of the area of square PQRS to the area of square ABCD is 5/9

<h3>Area of square ABCD</h3>

Assume the measure of the side lengths of the square ABCD is 1, then the area of the square ABCD is:

A_1 = 1 \times 1

A_1 = 1

See attachment for the diagram that represents the relationship between both squares.

<h3 /><h3>Pythagoras theorem</h3>

The measure of length PQ is then calculated using the following Pythagoras theorem:

PQ^2 = (\frac 13)^2 + (\frac 23)^2

Evaluate the squares

PQ^2 =\frac 19 + \frac 49

Add the fractions

PQ^2 =\frac 59

<h3>Area of square PQRS</h3>

The above represents the area of the square PQRS.

i.e.

A_2 =\frac 59

So, the ratio of the area of PQRS to ABCD is:

Ratio = \frac{A_2}{A_1}

This gives

Ratio = \frac{5/9}{1}

Ratio = \frac{5}{9}

Hence, the ratio of the area of square PQRS to the area of square ABCD is 5/9

What is a possible value of sin(theta) when cos2(theta)=0.21
podryga [215]
We know that

cos²(theta)=0.21
sin²(theta)+cos²<span>(theta)=1
</span>sin²(theta)=1-cos²(theta)------> sin²(theta)=1-(0.21)-----> 0.79
 sin(theta)=√0.79
 sin(theta)=0.89

the answer is
the value of  sin(theta) is 0.89

Find the speed<br><br>Example:      396  miles in 6 hours
Ivanshal [37]
To find the speed with given distance and time you just have to divide the distance by time. In this situation it's 396 miles in 6 hours, so it's 396 / 6 = 66 miles in 1 hour. So the speed is 66 mph.

Write the faction ration for each of the following.<br> If m
Aleksandr-060686 [28]

Answer:

\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0

Step-by-step explanation:

In any right triangle, the following is true:

The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)

The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus,

\text{3. }\\\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1},

\text{4. }\tan 68^{\circ}=\frac{GI}{2},\\GI=2\tan68^{\circ}=4.95017370683\approx \boxed{5.0}
