Answer:

BC = 54 units
m∠KJL = 22°

Step-by-step explanation:

BD is the perpendicular bisector of AC because AD = DC and DB⊥AC, therefore AB = BC

6x = 9x - 27
9x - 6x = 27
3x = 27
x = 9

BC = 9x - 27 = 9*9 - 27 = 81 - 27 = 54

-----------------------

JL is angle bisector of KJM, because KL = ML and KL⊥JK & ML⊥JM, therefore

m∠KJL = m∠MJL
4x + 6 = 3x + 10
4x - 3x = 10 - 6
x = 4

m∠KJL = 4*4° + 6 = 22°

Answer:

BC=54

m<KJL=22°

Step-by-step explanation:

6x=9x-27

27=3x

x=9

9(9)-27=54

BC=54

4x+6=3x+10

x=4

4(4)+6=22

m<KJL=22°
