I'm enraged at this math problem and I really need help please

Question

Sarah is designing a rectangular garden. The garden’s base must be 25.2 feet, and the ratio between the garden’s hypotenuse and height must be 13 : 5. Find the length of the garden’s hypotenuse and height.

Answer 1

Use Pythagoras (don't get enraged with him!),

(13x)² = (25.2)² + (5x)²

Can you solve for x and answer?
