The angle is 67°.

The two sides of the triangle given are the side adjacent to the angle (the distance from the house) and the hypotenuse (the length of the ladder).

adjacent/hypotenuse is the ratio for cosine:

cos x = (5/13)

To solve this, we will take the inverse cosine:

x = cos⁻¹ (5/13) = 67
