The answer is C. Because the side triangles inner corner is 51 so the inner corner of the big train fled are 129. 129 + 20 equals 149 and 180 - 149 equals 31.
Answer:
D
Step-by-step explanation:
Lets look at the numbers
sqrt(4) = 2 which is a rational number
sqrt(5) cannot be simplified, it is an irrational number
-6/5 a ratio of integers, which is the definition of a rational number, so it is a rational number
3.5 = 35/10 a ratio of integers, which is the definition of a rational number, so it is a rational number
.555555 = 5/9 a ratio of integers, which is the definition of a rational number, so it is a rational number
Rational numbers: sqrt(4), -6/5, 3.5 , .5555(repeating)
Irrational numbers: sqrt(5)
