In a 45-45-90 right triangle, what is the ratio of the length of one leg to the length of the other leg? O A1: O B. 2:1 O C. 1:1 D. 2:1

C. 1:1

Step-by-step explanation:

In a 45 45 90 right triangle, the side lengths for the legs are both

x and the length of the hypotenuse is

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
