Answer:
[tex]x=33.8[/tex]
Step-by-step explanation:
I assume these are similar triangles
x and 26 are similar sides since these are isosceles triangles.
So we can make a ratio since 20 and 26 are similar and 26 and x are too
[tex]\frac{26}{x} =\frac{20}{26}[/tex]
Cross multiply
[tex]26(26)=20x[/tex]
[tex]676=20x\\[/tex]
Divide both sides by 20
[tex]33.8=x[/tex]
I hope this helps
