Question

The following two triangles are similar find x

Answer 1

Your answer would be 5.
Scale factor= 5 because 45/9= 5
Since it’s a dilation you use the scale factor to find x
So 25/5= 5

Answer 2

5

Explanation:

As we can see they are similar triangles then

the ratio of the corresponding sides are equal then

x /25 = 9/45

x = 25 * 1/ 5

x = 5
