Step-by-step explanation:
Answer:
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

Answer:
x = 3
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
10x + 2 is an exterior angle of the triangle, thus
10x + 2 = 2x + 1 + 25
10x + 2 = 2x + 26 ( subtract 2x from both sides )
8x + 2 = 26 ( subtract 2 from both sides )
8x = 24 ( divide both sides by 8 )
x = 3
