Question

HELP ASAP PLEASE!!!!

Answer 1

for this problem the steps are below

recall pythagorean theorem

`a {}^(2) + b {}^(2) = c {}^(2)`
where and and b are the legs of the right triangle and c is the hypotenuse


`4 {}^(2) + 4 {}^(2) = d {}^(2)`
apply Pythagorean theorem

`√(16 + 16 ) = d`
square each 4 and take the square root of both sides

`√(32) = d`
simplify

reduce the radical
FINAL ANSWER

`4 √(2) = d`

or you can simply see that it's a 45 45 90 triangle and know that the hypotenuse d equal one of the legs times the square root of 2
