Question

PLEASE HELP DO SOON!!!

What is the length of CD?
What is the length of AB? Round answer to the nearest hundredth.

Answer 1

CD=14

AB=9.17

Explanation:

to understand this

you need to know about:

• circle

let's solve:

according to the question

• DF×DG=CD×DE

1. substitute the value of DF,DG, and DE:3×4=CD×2
2. simplify multiplication:12=2CD
3. simplify substraction:2CD/2=12/2
4. therefore CD=6

SECOND QUESTION:

first find the measure of BE

• 6+2+6
• 12+2
• 14

according to the question

• AB²=BE×BC

square both sides

• 
  `\sqrt{AB^(2)}=√(BE* BC)`
• 
  `AB=√(BE* BC)`

substitute the values of BE and BC

• 
  `AB = √(14 * 6)`

simplify multiplication:

• 
  `√(84)`

simplify redical:

• 9.17
