The length of the shorter wire is 12 cm

Step-by-step explanation:

Let us assume that the 27 cm wire is cut into two pieces of length x cm and so the longer part would be x+3 cm.

Now we know that the total length of the wire is 27cm so

x+(x+3) = 27

2x+3 = 27

2x = 27-3

2x = 24

x = 12 cm

What is x equal to????

Ksju [112]

Answer:

x = 20

Step-by-step explanation:

The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is

4x + 2 + x + 78 = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20
