Answer:
zero
Step-by-step explanation:
The given measurements are:
A= 61º, a = 23, b = 24
In a triangle, the sum of the angles therein is 180°. A triangle is a figure with three sides.
With internal angles summing up to 180°
To know if the given angles are of a triangle, the must add up to 180°;
So;
Summation = 61 + 23 + 24 = 108°
This is not a triangle.
Therefore, from the summation of the angles given, we can see that they do not add up to the sum of angles within a triangle.
Answer:
3/4 or 0.75
Step-by-step explanation:
A set has closure under an operation if performance of that operation on members of the set always produces a member of the same set; in this case we also say that the set is closed under the operation.
A closure property is a certain rule that holds <u>if it is true for all elements of a set under the given operation</u> and a closure property does not hold <u>if there is at least one pair of elements that do not follow the closure property under the given operation.</u>
Therefore, Emma is correct, because you can find a counterexample (7:2=3.5) that gives you a non-integer answer.
Answer: correct option is B
Answer:
7 4/5
Step-by-step explanation:
Dividing 5 into 39 results in 7 with a remainder of 4. Thus,
39/5 = 7 4/5
