4. Here you would use the Pythagorean Theorem. a² + b² = c²
In this case a and b are the same, so : a² + a² = c² would also work.
a = 5√2 so: (5√2)² + (5√2)² = c²
Do you know where to go from here?
Whats the problem? just substitute. For example: 3x-5 if x=4 so what you do is this; 3(4)-5=7
Okay so i cant just post what the answer is i have to type something.
but anyways this is the answer: t= 4.56
