Answer:
x = 33
Explanation:
You can find the greatest common factor of the triangle side lengths on the right. It is 9. Both triangles are scaled versions of 3-4-5 triangles. Divide any side from the left triangle by its respective side length from 3-4-5, in this case 44/4 or 55/5. We can see that the scalar for this triangle is 11. This means the 3- the shortest side length. Is actually 3 x 11 = 33.
Therefore x = 33.
