Complete the following proof. Given: AB, CD are diameters. Prove: BD=CA

Step-by-step explanation:

1. if AB& CD are diameters, then AB=CD, and then OA=OB=OC=OD - radiuses.

It means, OA=OB and OC=OD.

2. m∠(AOC)=m∠(BOD);

3. according to the 1. & 2 ΔAOC=ΔBOD, then BD=CA

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
