Answer:
5
Step-by-step explanation:
What we have to know is that when two triangles are similar their sides will always be proportional. So we will create a proportion that goes like this...
but since it doesn't tell us the exact value of triangle 1. We will have to add 3 and 12 to get 15 which is the base of the first triangle. Now we're ready to write the proportion.
![\frac{4x}{15}=\frac{3x+1}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B15%7D%3D%5Cfrac%7B3x%2B1%7D%7B12%7D)
Now we cross multiply and solve the equation...
![48x=15(3x+1)\\48x=45x+15\\3x=15\\x=5](https://tex.z-dn.net/?f=48x%3D15%283x%2B1%29%5C%5C48x%3D45x%2B15%5C%5C3x%3D15%5C%5Cx%3D5)
So the value of x is 5.
