There are n! ways to arrange n different elements
This means there are 3! or 6 different arrangements of any 3 elements.
In this case namely,
abc
acb
bac
bca
cab
cba
We have AB + BC = AC.
2x + 7 = 6x - 5
2x - 6x = - 5 - 7
-4x = -12
x = -12/-4
x = 3
We both know that x is 3.
We also want AB.
AB = 2x
AB = 2(3)
AB = 6

Answer:
P' = 1/3 P
reflection in the y-axis just changes the sign of all the x-values.
Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P
It is, however, similar to P.
Answer: the area is 84 cm^2
Answer:
∠A = 88°
Step-by-step explanation:
= 180° - (50° + 38°)
= 180° - 88°
= 92°
∠A + 92° = 180°
∠A = 180° - 92°
∠A = 88°
