oksian1 [2.3K]

Answer:

Segment B C and Segment P N

Step-by-step explanation:

we know that

Line segments are congruent if they have the same length

In this problem

we have

Segment L.M ≅ Segment F.A

Segment M.N ≅ Segment A.B

Segment P.N ≅ Segment B.C

Segment P.J ≅ Segment C.D

Segment J.K ≅ Segment E.D

Segment K.K ≅ Segment F.E

therefore

The answer is

Segment B C and Segment P N

1.8 miles

Step-by-step explanation:

For this case we can model the problem as a rectangle triangle.

We know:

Length of the sides of the triangle

We want to know:

Length of the hypotenuse

Using the Pythagorean theorem we have:

$d=\sqrt{3^{2} +3^{2} }\\d = \sqrt{2(3^2)} \\d = 3\sqrt{2} \\d = 4.2 miles$

Then, the distance that he would have saved if he travels directly is:

$3 + 3 - 4.2 = 1.8 miles$

Answer:

he would have saved:

1.8 miles

A backyard pool has a concrete walkway around it that is 3 feet wide on all sides. The total area of the pool and the walkway is

Sloan [31]

Answer:

$x \approx 21.080\,ft$ , $y = 29.080\,ft$

Step-by-step explanation:

The total area of the pool and the walkway is:

$(x + 6\,ft)\cdot (y + 6\,ft) = 950\,ft^{2}$

$(x + 6\,ft)\cdot (x + 14\,ft) = 950\,ft^{2}$

$x^{2} + 20\cdot x + 84\,ft^{2} = 950\,ft^{2}$

$x^{2} + 20\cdot x - 866\,ft^{2} = 0$

The roots of the second-order polynomial is:

$x_{1} \approx 21.080\,ft$ and $x_{2} \approx -41.081\,ft$

The only possible root is:

$x \approx 21.080\,ft$

The other dimension of the pool is:

$y = x + 8\,ft$

$y = 21.080\,ft + 8\,ft$

$y = 29.080\,ft$

A circle with circumference 20 has an arc at 72 central angle. what is the length of the arc

Vsevolod [243]

Answer:

4 units

Step-by-step explanation:

$\because \: l = \frac{ \theta}{360 \degree} \times c \\ \\ \therefore \: l = \frac{72 \degree}{360 \degree} \times 20 \\ \\ \therefore \: l = \frac{72 \degree}{18\degree} \\ \\ \therefore \: l = 4 \: units$
