12-29.
Use the diagram of ⊙C below to answer the questions below it. Homework Help ✎
If m
x = 28°, what is ?If AD = 5 and BD =
, what is the area of ⊙C?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.
