The angles are congruent meaning that you can set them equal to each other:
26 = 5x + 11
Now you can solve for x
26 - 11 = 5x + (11 - 11)
15 = 5x
15/5 = 5x/5
x = 3
Hope this helped!

A unit fraction means 1 unit is the value of the numerator. This means 1 is in the numerator.
All the triangles are isosceles meaning that they have to sides that are equal
Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
