Answer:
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°

Answer:
g(x) = 
Step-by-step explanation:
f(x) = 3x + 5
f[g(x)] = 3[g(x)] + 5
⇒ 3[g(x)] + 5 = x + 4
⇒ 3[g(x)] = x + 4 - 5
⇒ 3[g(x)] = x - 1
⇒ g(x) =
Your answer is C. Hope this help :D
