Question

For questions #7 and 8, find each value or measure.

Answer 1

EF = 26

x = 10

Explanation:

7.

Since it is given that EF and arc CD are equal, we can set up an equation to find the value of EF.

• EF=CD

Substitute the given values of CD and EF into the equation:

• 41−5x=9x−1

Solve for x by adding 5x to both sides and adding 1 to both sides:

• 42=14x

Divide both sides by 14 to find the value of x:

• x=3

Substitute the value of x into the equation for EF:

• EF=41−5x
• EF=41−5(3)
• EF=26

So the value of EF is 26.

Answer 2

7 ans=26

Explanation:

7)

both chords are equal so

9x-1=41-5x

14x=42

x=3

now,

41-5*3=26
