The right triangle given below was drawn using a scale factor of 1/15. Each small square on the grid has a side length of 2 inches.

Since each small square has a side length of 2 inches, we can say that each large square on the grid has a side length of 30 inches (15 small squares make up one large square).

Using the scale factor of 1/15, we can find the side lengths of the triangle.

The horizontal leg of the triangle has a length of 5 small squares, which is equal to 10 inches.

The vertical leg of the triangle has a length of 3 small squares, which is equal to 6 inches.

Thus, the measurements of the right triangle are as follows:
- Horizontal leg: 10 inches
- Vertical leg: 6 inches
- Hypotenuse: √(10^2 + 6^2) = √(100 + 36) = √136 ≈ 11.66 inches

Therefore, the right triangle has dimensions of 10 inches by 6 inches by approximately 11.66 inches.
