100 points! Mhanifa please help. Look at the picture attached. I will mark brainliest!

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°

Step-by-step explanation:

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

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 = 4*4° + 6 = 22°

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
