The missing side length of the right triangle is 20.81
How to determine the solution to the right triangle
From the question, we have the following parameters that can be used in our computation:
The right triangle
The missing length in the right triangle can be calculated using the Pythagoras theorem
So, we have
h² = 17² + 12²
Evaluate
h² = 433
Evaluate
h = 20.81
Hence, the solution to the right triangle is 20.81
