2 triangles are shown. The first triangle has side lengths 15, 15, and 21. The second triangle has side lengths 20, 20, x. What value of x will make the triangles similar by the SSS similarity theorem? x =

28

Step-by-step explanation:

The ratio of the sides must be the same

15           21

=

20           x

Using cross products

15x = 20*21

Divide each side by 15

15x/15 = 20*21/15

x =28

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
