What is the length of x in the diagram below? topic

see the attached figure with letters to better understand the problem

Step 1

Find the length of BD

we know that

In the right triangle ABD

BD=AD ------> because is a triangle

so

Step 2

Find the length of BC

In the right triangle BCD

we have

substitute the values and solve for x

therefore

the answer is

The length of x is

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
