Need help which one is it <br> a)x=7<br> b)x=12<br> c)x=20
Svetach [21]

- you can use the pythagorean theorem for this.

a^2 + b^2 = c^2

12^2 + 16^2 = c^2

144 + 256 = c^2

400 = c^2

- square root this.

c = 20

therefore, x = 20.

so option C.

What is the value of x?
lawyer [7]

Answer:

x=19, DE=84, EF=36

Step-by-step explanation:

Since the total value of DF is 120, DE and EF must add up to 120. Therefore:

4x+8+2x-2=120

Combine like terms:

6x+6=120

Divide both sides by 6:

x+1=20

Subtract 1 from both sides:

x=19

This means that DE is 4(19)+8=84, and EF is 2(19)-2=36.

Hope this helps!
