The question is below thanks
iren [92.7K]

Answer:

10.02 units

Step-by-step explanation:

FH = \frac{82}{360} \times 2 \pi r (Multiplying the circumference of the circle by the arc's degree over the total degree of the circle will find the length of the arc FH)

FH = \frac{82}{360}\times 2 \pi (7)

=\frac{82}{360}\times14\pi

=\frac{287\pi}{90}

=10.02 (to the nearest hundredth)

∴ The length of the arc FH is 10.02 units to the nearest hundredth.

Hope this helps :)

If m ∠4 = m ∠5, then r||s. Summarize the postulate or theorem that makes this a true statement.
coldgirl [10]

The statement, m∠4 = m∠5, then then r||s is true based on the converse of corresponding angles theorem.

<h3>What is the Converse of Corresponding Angles Theorem?</h3>

Based on the converse of corresponding angles theorem, if two corresponding angles, angles 4 and 5 are congruent or equal to each other, then the lines on which they lie on, lines r and s are congruent.

Therefore, based on the converse of corresponding angles theorem, m∠4 = m∠5, then then r||s.
