Answer:
x = 115.4
Step-by-step explanation:
Let x be the diagonal of the rectangle and hypotenuse of the triangle.
Using Pythagoras' Theorem,
hypotenuse² = opposite ² + adjacent²
x² = 10² + 115²
x² = 100 + 13225
x² = 13, 325 Take the square roots of both sides
x = √13,325
x = 115.4339638
x = 115.4 to the nearest tenth
