Answer:

16 ft

Step-by-step explanation:

The equation is a^2+b^2=C^2

a= 30^2 = 900

b= we need to find

c= 34^2=1156

so the equation looks like this so far

900 + B^2 = 1156

we are going to subtract 900 so B^2 can be alone

1156 - 900 = 256

Now the equation looks like =

B^2 = 256

now we square root 256

which gives you 16

B = 16

A triangle with vertices D, E, and F are plotted on the coordinate plane at (0, 5). (2, 0), and (-4, 2), respectively. When cons

rodikova [14]

Given:

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2).

To find:

The intersection point of medians DG and EH.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

$Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)$

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2). So, the centroid of the triangle is

$Centroid=\left(\dfrac{0+2+(-4)}{3},\dfrac{5+0+2}{3}\right)$

$Centroid=\left(\dfrac{-2}{3},\dfrac{7}{3}\right)$

$Centroid=\left(-0.666...,2.333\right)$

Round each coordinate to the nearest tenth.

$Centroid=\left(-0.7,2.3\right)$

Therefore, the correct option is C.

What is the scale factor in simplest terms?<br><br> Any help is appreciated ty :)

VMariaS [17]

Answer:

1 2/3 units

Step-by-step explanation:

We have to divide 10/6 to find the difference between the two shapes.

10/6= 1 2/3

Since there is no unit here, then we can just write the answer as 1 2/3 units.

Hope this helped :)
