Question

Solve to find missing length

Answer 1

`\huge\pink{ \boxed{\therefore \: m = n = (7)/( √(2) ) }}`

Explanation:

Given triangle is a 45°-45°-90° angled triangle.

`\therefore \: m = n \\ (sides \: opposite \: to \: 45 \degree \: \angle s) \\ \therefore \: m = n = (1)/( √(2) ) * 7 \\ (by \: 45 \degree - 45 \degree - 90 \degree \: theorem)\\ \huge\purple{ \boxed{\therefore \: m = n = (7)/( √(2) ) }}`
