It seems like you've uploaded two images from a mathematics word problem assignment involving right triangles. Let me help break down what you're working on.

From the images:

1. Right Triangle Properties:

   • In the first image, you are asked to find the lengths of the sides of the lower triangle.
   • The provided values for the longer leg (48 ft), shorter leg (36 ft), and hypotenuse (60 ft) correspond to a 3-4-5 Pythagorean triple scaled by 12, which fits perfectly since $3^2 + 4^2 = 5^2$ and $36^2 + 48^2 = 60^2$.

2. Second Image:

   • The setup involves two adjacent right triangles with a common leg, forming a larger triangle.
   • The hypotenuse of the lower triangle is $x + 12$, and the short leg is $x - 12$.
   • The hypotenuse of the upper triangle is 21 feet.

The problem is leading towards using the Pythagorean Theorem in both triangles to find the value of $x$. Let me work through the problem for you step by step.
