Answer the 2 questions

1. yes

2. no

Step-by-step explanation:

1. Yes.

since all our sides are the same, it doesn't matter which is the shorter or longer

a+a > 2a for all lengths a>0, since lengths of triangles can only be positive and greater than 0

equilateral triangles exist for a reason

2. no

a triangle will have exactly 180 degrees, no less, no more

30+70+110 >180

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the answer is a.
