Answer:

5.78

Step-by-step explanation:

S= $\frac{1}{2}$ (a+b)*h

a = 1.8

b = 5

h = 1.7

S = $\frac{1}{2}$ (1.8+5)*1.7

S = (6.8*1.7)/2

S = 11.56/2

S = 5.78

What is the name of the point from which a dilation is drawn?

dedylja [7]

For this case, the first thing you should do is know that dilation is a transformation that is used<em> to lengthen or shorten a geometric figure. </em>

Geometric figures can be triangles, squares, circles, or any polygon.

There is a point on the plane, at which the dilation begins to be drawn.

This point on the plane is what we know as the center of dilation .

Answer:

B. the center of dilation

Answer:

Area $=62.5\sqrt{6}$ square units

$AB=5\sqrt{15}$ units

$BC=5\sqrt{10}$ units

Step-by-step explanation:

In a right triangle the altitude drawn to the hypotenuse is the geometric mean of the segments at which this altitude divides the hypotenuse.

So,

$BD^2=15\cdot 10\\ \\BD^2=150\\ \\BD=\sqrt{150}=5\sqrt{6}\ units$

a. The area of the triangle ABC is

$A_{ABC}=\dfrac{1}{2}\cdot BD\cdot AC=\dfrac{1}{2}\cdot 5\sqrt{6}\cdot (15+10)=\dfrac{125\sqrt{6}}{2}=62.5\sqrt{6}\ un^2.$

b. The legs of the right triangle are geometric means of the segment adjacent to this leg and the hypotenuse, so

$AB^2=AD\cdot AC=15\cdot 25\Rightarrow AB=5\sqrt{15}\ units\\ \\BC^2=CD\cdot AC=10\cdot 25\Rightarrow BC=5\sqrt{10}\ units$

15x=3x+120 <br><br> Show answer

inn [45]

15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100
