Find the length of the hypotenuse of an isosceles right triangle whose legs are 1 unit in length.

check the picture below

and isosceles triangle, has two equal sides, thus, sides "a" and "b" for the triangle to be an isosceles, have to be equal

The length of the hypotenuse of an isosceles right triangle whose legs are 1 unit in length is; 1.414 units

we have;

Lengths of 2 legs as;

x = 1

y = 1

Hypotenuse length is;

h = √(1² + 1²)

h = √2

h = 1.414 units

where is the picture

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
