What are the steps for using a compass and straightedge to construct the bisector of ZA?

romanna [79]

The order of the steps is:

Step 1. is the fifth statement

Step 2. is the first statement

Step 3. is the second statement

Step 4. is the third statement

Step 5. is the fourth statement

Step-by-step explanation:

Lets revise the steps of construct the bisector of ∠ A

Steps:

1. Place the point of the compass on point A and draw an arc that

intersects the sides of ∠A

Label the points of intersection as points B and C

2. Place the point of the compass on point B and draw an arc in the

interior of the angle

3. Without changing the opening of the compass place the point of

the compass on point C and draw another arc in the interior of the

angle

4. Label the intersection of the arcs in the interior of the angle as

Point D

5. Use the straightedge to draw AD ray

From the steps above

The order of the steps is:

Step 1. is the fifth statement

Step 2. is the first statement

Step 3. is the second statement

Step 4. is the third statement

Step 5. is the fourth statement

A rectangular parcel of land has an area of 3,000 ft2. A diagonal between opposite corners is measured to be 10 ft longer than o

Kazeer [188]

Answer:

40 ft × 75 ft

Step-by-step explanation:

Let x be the one side ( in feet ) of the rectangular parcel,

So, the diagonal between opposite corners = ( x + 10 ) feet,

Let y be the other side of the rectangle ( adjacent to side x ),

The area of the rectangle,

A = x × y,

According to the question,

A = 3000 square ft,

$\implies xy = 3000\implies y=\frac{3000}{x}$

∵ In a rectangle,

$D^2=a^2+b^2$

Where, a and b are the adjacent side of the rectangle and D is the diagonal,

$(x+10)^2 = x^2 + y^2$

$(x+10)^2 = x^2 + \frac{9000000}{x^2}$

$x^2(x+10)^2 = x^4 + 9000000$

$x^2(x^2+100+20x) = x^4 + 9000000$

$x^4+100x^2 + 20x^3 = x^4 + 9000000$

$20x^3 + 100x^2 - 9000000=0$

$x^3 + 5x^2 - 450000 = 0$

By graphing the equation,

We found that,

The only real zeros of the equation is at x = 75,

Hence, the one side of the rectangle = 75 ft,

And, second side = $\frac{3000}{75}$ = 40 ft

Hence, the dimension of the land is 40 ft × 75 ft
