Answer:
So each interior angle measurement of the regular triangle is 60 degrees.
Step-by-step explanation:
If the triangle is regular, this means all the side measurements are congruent to each other and that all the angle measurements are congruent to each other.
If the sum of the angles in a triangle is 180 degrees and you know they are each the same then you could either solve x+x+x=180 or know we are just dealings with an equiangular triangle in which all angles have measurement 60 degrees.
If need more convincing, let's actually solve:
x+x+x=180
3x=180
x=180/3
x=60
So each interior angle measurement of the regular triangle is 60 degrees.
Here it is.. you need to calculate some numbers
Answer:
4
Step-by-step explanation:
<u>Answer:</u>
A. (x+5)
<u>Step-by-step explanation:</u>
We are given a quadratic expression 
which we will factorize to see which of the given options is a binomial factor of it.
Finding the factors of 15 such that when added, they give a result of 8.
Therefore, we can see that 
is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
Digit 1:1,3,5,7, or 9.
Digit 2: 0,1,2,3,4,5,6,7,8 or 9.
4*10= 40 possible codes.
