What is the length of leg s in the right triangle shown? A.

B.
2

C.

D.
5

it's 5

Step-by-step explanation:

you use x : x : x square root of 2 ratio

5 units

Step-by-step explanation:

we can identify this as an isosceles triangle because both angles are equal (= 45 deg). Hence we can also conclude that the vertical leg of the triangle must also be "s"

We an also identify this as a right triangle because we have one angle that is 90 degrees. Hence we can use the Pythagorean formula to solve this (see attached for reference)

(5√2 )² = S² + S²

(5)²(√2 )² = 2S²

(25)(2) = 2S²

25 = S²

S = √25

S = 5 units

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
