If you use a ruler and if it's more than 120° its not a right triangle it has to be 120°
Answer:
31.5
Step-by-step explanation:
You need to prove that <A = <E
since c is the midpoint of line AE then AC = EC
i dont remember the name of the theroem that states that when a triangle has two sides and an angle in common that it is congruent i think it called SAS congruence therom. use that to prove that the <| s are congruent then use CPCTC to prove that <A = <E. then prove that they are || by usint the int angle therom.
Answer:
Yes
Step-by-step explanation:
Consecutive numbers differ by one, which means that if you start with a certain integer 
, you obtain the next integer by adding one.
So, if you start with 
, the three consecutive numbers are
The sum of these three numbers is
This number is divisible by 3 because you can write it as
Note that this is true in general: the sum of three consecutive numbers is always divisible by three, because it is three times the middle number.
