question 1 is a
question 2 is d
Step-by-step explanation:
What is the average score? 79, 82, 85, 91, 97, 73, 88, 87, 85, 92, 90, 85, 86, 91, 94, 85, 92

79+82+85+91+97+73+88+87+85+92+90+85+86+91+94+85+92=1482 divided by 17 ( the amount of numbers) = 87.17
Answer:
x = -15
Step-by-step explanation:
7 + (2/5)x = 1
First, divide two by five to get 0.4, then substitute in the choices given (remembering that you must also add seven afterward).
0.4*-15 = -6 -6 + 7 = 1 = 1
And there you have it!
*It is important to double check your answer by testing other numbers as well.
Given:
The interior angle of a regular polygon is 132 degrees.
To find:
The given statement is possible or not.
Solution:
Let as assume the interior angle of a regular polygon with n vertices is 132 degrees.
Then, the exterior angles are
We have, n vertices. So, the number of exterior angles is n.
Sum of all exterior angles = 48n degrees
We know that, sum of all exterior angles of a regular polygon is always 360 degrees.
Number of vertices is always a whole number. So, it cannot be a fraction value.
So, our assumption is wrong.
Therefore, a regular polygon cannot have an interior angle of 132 degrees.
