12-29.
  1. Use the diagram of ⊙C below to answer the questions below it. Homework Help ✎

    1. If mx = 28°, what is ?

    2. If AD = 5 and BD = , what is the area of ⊙C?

    3. If the radius of ⊙C is 8 and if = 100°, what is BD ?

D is a right angle. Why?

Use the Pythagorean Theorem to find the length of AB.
How can you use that length to find the area?

measure of arc AD = 124°

25π un2

Draw radius CD. Use the fact that ∠BCD = 100° and the Law of Sines to find BD.
