The area of a triangle can be determined by knowing 2 sides and their included angle of a certain triangle. Since both sides are equal, then they would just be denoted by a squared entity. This is done as follows:
A = x² sin∅
32 = x² sin (5*pi/6)
Make sure your calculator is in rad form.
32 = x² (1/2)
x = 8
Thus, each side is 8 cm.
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:
The numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.
Step-by-step explanation:
Two numbers are consecutives, when their difference is equal to 1. The area of the triangle is determined by the following formula:
Where 
is the shortest length of the triangle, measured in centimeters.
And we get the following second-order polynomial:
(1)
If we know that 
, then the shortest length of the triangle is:
and 
Since length is a positive variable, the only possible solution is:
Then, the numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.
Answer:
6²
Step-by-step explanation:
Using the rule of exponents
⇔ 
, then
= 
= 6²
