Answer: 2 cm
Step-by-step explanation:
Here we are given two right triangles. The length of x could be one of the sides of one right triangle. Split this triangle in half. Now we have a side length of 1.5 cm and a hypotenuse of 2.5 cm. Use the pythagorean formula [tex]a^2+b^2=c^2[/tex] we can rearrange this to [tex]b = \sqrt{c^2-a^2}[/tex] C is our hypotenuse length (2.5), always, and A can be our known side length (1.5). Plug in the values and you obtain a final value of 2 for B, or in this case X.
