Because all the angles are congruent (the same), this is an equilateral triangle. All equilateral triangles have congruent angles and congruent sides, so all sides has to be 14.
Answer:
The probability is 2/5
-7
Step-by-step explanation:
Seems like the pattern is adding and then subtracting the next square number up:
7 + 4 = 11
11 - 9 = 2
2 + 16 = 18
so 18 - 25 = -7 is the next number
5/x = 10/12
10x = 5•12
10x = 60
x = 60/10
x = 6
