1. ## circle help. i hate these.

Use pic 11 for 11 and pic 12 for 12

11. Given: CH = 3, DJ = 3, EJ = 3, AJ = 2, mDG = 56 degrees

AH =

A. 3
B. 2
C. 4
D. 6

m<AJD =

A. 124°
B. 90°
C. 56°
D. 34°

12. Given: mAD = 100 degrees, mAB = 40 degrees, mBC = 80 degrees

mCD =

A. 140°
B. 100°
C. 160°
D. 120°

m<C =

A. 70°
B. 20°
C. 50°
D. 40°

11. Given: CH = 3, DJ = 3, EJ = 3, AJ = 2, mDG = 56 degrees

AH = 2, because BC=ED, and congruent chords are equidistant from the center of a circle

A. 3
B. 2
C. 4
D. 6

m<AJD = 90 degrees. If a radius bisects a chord, then it is perpendicular to the chord.

A. 124°
B. 90°
C. 56°
D. 34°

12. Given: mAD = 100 degrees, mAB = 40 degrees, mBC = 80 degrees

mCD = 360 - (100 + 40 + 80) = 140

A. 140°
B. 100°
C. 160°
D. 120°

m<C = 1/2 arc AB = 20. The measure of an inscribed angle is one-half the measure of its intercepted arc.

A. 70°
B. 20°
C. 50°
D. 40°

3. ## thanks

thanks a lot again.
