The length of AD of the given quadrilateral is:

AD = 4.6 cm

What is the length of the Quadrilateral?

Using trigonometric ratios, we can see that:

3/AC = cos 35

AC = 3/cos 35

AC = 3.66 cm

Using law of cosines, we have:

AD² = 5² + 3.66² - 2(5 * 3.66) * cos 61

AD² = 20.797

AD = √20.797

AD = 4.6 cm
