Question

AB\\DC, AO/OC=BO/OD then find the value of x if OA=2x+7OB=4x,OD=4x-4 and OC=2x+4​

Answer 1

Answer:

X=7

Step-by-step explanation:

OA/OC=OB/OD

2x+7/2x+4=4x/4x-4

Cross multiplication

2x+4×4x=2x+7×4x-4

8x^2+16x=8x^2+28x-8x-28

8x^2 cancel

16x=20x-28

20x-16x-28=0

4x-28=0

4x=28

x=28/4

x=7
