It remains the same. if the shape is the same then so is it's angle measure.
Answer:
<h2>x = 8</h2>
Step-by-step explanation:
<em>Look at the picture</em>.
ΔABC and ΔACD are similar. Therefore corresponding sides are in proportion:
![\dfrac{AB}{AC}=\dfrac{AC}{AD}](https://tex.z-dn.net/?f=%5Cdfrac%7BAB%7D%7BAC%7D%3D%5Cdfrac%7BAC%7D%7BAD%7D)
We have
![AB=2+6=8,\ AC=x,\ AD=2](https://tex.z-dn.net/?f=AB%3D2%2B6%3D8%2C%5C%20AC%3Dx%2C%5C%20AD%3D2)
Substitute:
<em>cross multiply</em>
![x^2=(8)(2)\\\\x^2=16\to x=\sqrt{16}\\\\x=8](https://tex.z-dn.net/?f=x%5E2%3D%288%29%282%29%5C%5C%5C%5Cx%5E2%3D16%5Cto%20x%3D%5Csqrt%7B16%7D%5C%5C%5C%5Cx%3D8)
A fraction is a decimal or percent turned into an equal number out of a whole number and part of it. It will include a numerato on top and a denominator on the bottom. Hope this helped!
