A carpet Measures 7 feet long and has a diagonal Measurement (85). Find the width of the carpet.

The width of the carpet is the square root of about 84.7 feet  or the square root of 7176.

Step-by-step explanation:

So a carpet is in a shape of a rectangle and we know the length of the carpet is 7 feet .

so we could use the Pythagorean theorem rule  a^ 2 + B^2 =C^2 to find the width.

so  7^2 + b^2= 85^2    where 85 is the hypotenuse and  7 is one of the legs.

49 + b^2 = 7225

-49             49

    b^2=  7176

b= 84.7

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
