Answer:
Step-by-step explanation:
Corresponding angles equal 180 degrees when added
6x + 3x = 180
9x = 180
x = 20
angle CBD is 60 and angle GFH is 120
3(20) = 60
6(20) = 120
The chords ar of equallength so
3x - 15 = 2x - 4
x = -4 + 15 = 11
So the chord JK = 3(11) - 15
= 18 answer
the first one is (-4,-2)
6.23
