Check the picture below

the triangles are similar, the angles are congruents then

so... just add them up, and divide by 2, or set them as rational

Calcula los lados desconocidos del siguiente triángulo sabiendo que el perímetro mide 36 cm, el lado BC 10 cm y la altura sobre
nadezda [96]

Answer:

AC = 11.6 cm

AB = 14.4 cm

Step-by-step explanation:

To make the solution easier, we can draw the triangle, as in the image attached.

Let's call the side AC = x, and the bigger side AB = y

The height of 8 cm divide the bigger side in two parts, a and b, in the point H.

In the triangle CHB, we can use pythagoras formula to find the value of a:

a^2 + 8^2 = 10^2

a^2 = 100-64 = 36

a = 6

then, we have that a + b = y -> b = y - 6

Now, using the pythagoras formula in triangle CHA:

8^2 + (y-6)^2 = x^2

64 + y^2 - 12*y + 36 = x^2

x^2 - y^2 + 12*y = 100

From the perimeter of the triangle, we have that:

x + y + 10 = 36 -> x + y = 26 -> x = 26 - y

Then, using this value of x in the equation above, we have:

(26 - y)^2 - y^2 + 12*y = 100

676 - 52*y + y^2 - y^2 + 12*y = 100

40*y = 576

y = 14.4 cm

Now we can find x:

x = 26 - y = 26 - 14.4 = 11.6 cm

Identify the image of a triangle with vertices L(−3,4), M(−2,1), and N(0,2) under a dilation with a scale factor of −3 centered
Simora [160]

Answer:

  see below

Step-by-step explanation:

The image is reflected across the origin and enlarged by a factor of 3.

___

The first choice shows some funny combination of translation, rotation, and dilation. The last choice has point N invariant, which means that is the center of the (horizontal only) dilation. Neither of these matches the problem description.
