If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:
![\frac{2x+1}{3x}=\frac{10}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B1%7D%7B3x%7D%3D%5Cfrac%7B10%7D%7B14%7D)
(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).
Now, cross multiply and solve for x:
28x+14=30x
<em>*Subtract 28x from both sides to isolate the variable*</em>
14=2x
<em>*Divide both sides by 2*</em>
7=x
Hope this helps!!
