URGENT PLS HELP
Allisa [31]

Answer:

A) 3a = 180°

B) a+ 55° + 36° = 180°

C) x + y + z = 180°

Step-by-step explanation:

The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )

The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.

The terms don't have to be similar, for instance the B option,

a+ 55° + 36° = 180°

since you could find the value of a.

The same thing goes for C.

(Extra)

It is not D since x is multiplied with 3, not giving the sum.

It is not E since all the 3 terms are multiplied, not giving the sum.
