[angle A = angle X and angle C and angle Z are right angles]
Note: Write equations, use algebra. Use similar triangles, AAA similar triangles theorem, and/or Pythagorean theorem.
This material may consist of step-by-step explanations on how to solve a problem or examples of proper writing, including the use of citations, references, bibliographies, and formatting. This material is made available for the sole purpose of studying and learning - misuse is strictly forbidden.The triangles are similar and we have Pythagoras:
x² + y² = z²
a² + b² = c²
Since the triangles are similar there is a number t so that:
x = ta, y = tb, z = tc...
