Answer:
[tex] \huge\pink{ \boxed{\therefore \: m = n = \frac{7}{ \sqrt{2} } }}[/tex]
Step-by-step explanation:
Given triangle is a 45°-45°-90° angled triangle.
[tex] \therefore \: m = n \\ (sides \: opposite \: to \: 45 \degree \: \angle s) \\ \therefore \: m = n = \frac{1}{ \sqrt{2} } \times 7 \\ (by \: 45 \degree - 45 \degree - 90 \degree \: theorem)\\ \huge\purple{ \boxed{\therefore \: m = n = \frac{7}{ \sqrt{2} } }}[/tex]
