Answer:

x = 2

Step-by-step explanation:

all the angles in a triangle that are added together will equal 180 degrees

so having known that you will get this equation: \/

                                                                      2x+5+8x=25

                                                                      then you solve

8x+2x+5=25

10x+5=25

10x=20

x=2

Pete is ahead of nick by 11 meters. Oliver is ahead of manny by 10 meters. Oliver is ahead of pete by 5 meters. How far is the r
Leokris [45]

Answer:

<u>The runner in first place is 16 meters ahead of the runner in last place</u>

Step-by-step explanation:

There are 4 boys racing - Pete, Nick, Manny, and Oliver.

Pete is 11 meters ahead of Nick, Oliver is 10 meters ahead of Manny, and Oliver is ahead of Pete by 5 meters.

This means Oliver is ahead of the other three racers, putting him in first place, and Manny is between Nick and Pete.

So in order to find out the distance between the racer in first place (Oliver) and the racer in last place (Nick), add the distance between Oliver and Pete and the distance between Pete and Nick.

Add the distances: <u>5 + 11</u>

<u>Therefore, the runner in first place (Oliver) is 16 meters ahead of the runner in last place (Nick).</u>

What is the area of rectangle ABCD, if points A, B, C, and D have the following coordinates?
slega [8]

Answer:

The area of the rectangle ABCD is \frac{2}{5} square units.

Step-by-step explanation:

From statement we have that rectangle ABCD is formed by the following points: A(x,y) = (2, 5), B(x,y) = \left(\frac{8}{3}, 5 \right), C(x,y) = \left(\frac{8}{3}, \frac{28}{5}  \right), D(x,y) = \left(2, \frac{28}{5} \right). First, we calculate the length of each side by the Pythagorean Theorem:

AB = \sqrt{\left(\frac{8}{3}-2 \right)^{2}+ (5-5)^{2}}

AB = \frac{2}{3}

BC = \sqrt{\left(\frac{8}{3}-\frac{8}{3}\right)^{2}+\left(\frac{28}{5}-5\right)^{2} }

BC = \frac{3}{5}

CD = \sqrt{\left(2-\frac{8}{3} \right)^{2}+\left(\frac{28}{5}-\frac{28}{5}  \right)^{2}}

CD = \frac{2}{3}

DA = \sqrt{\left(2-2\right)^{2}+\left(5-\frac{28}{5} \right)^{2}}

BC = \frac{3}{5}

Which satisfies all minimum characteristics for a rectangle. The area of the rectangle ABCD is the product of its base and its height, that is:

A = \left(\frac{2}{3}\right)\cdot \left(\frac{3}{5} \right)

A = \frac{2}{5}

The area of the rectangle ABCD is \frac{2}{5} square units.
