Answer:
109
Step-by-step explanation:
Given that the figure is a rectangle, then the diagonal and two sides will form a right triangle. This means that the Pythagorean theorem can be applied. The Pythagoren theorem states;
[tex]a^{2} + b^{2} = c^{2}[/tex]
Where (a) and (b) are the legs or sides, and (c) is the hypothenuse also known as the diagonal or side opposite the right angle.
Substitute;
[tex]a^{2} + b^{2} = c^{2}\\\\60^{2} +91^{2} = c^{2}\\\\3600+8281=c^{2}\\\\11881=c^{2}\\\\109=c[/tex]
