How do you find the sum of the interior angles of a heptagon. Plz help!
1 answer:
Hey there!
The equation for finding the sum of the interior angles for a polygon with n sides is the following:
"Hepta-" means seven; thus, a heptagon has 7 sides.
Since a heptagon has 7 sides, n=7.
Now, let's plug in that value into the equation.
Thus, the sum of all interior angles in a heptagon is 900 degrees.
Have an awesome day! :)

Answer:
The best course grade your friend can earn is 0.867 = 86.7%.
The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.
Step-by-step explanation:
This is a weighed average problem, in which we multiply each grade by its weight.
We have that:
In 70% of the course, the friend has a grade of 81%.
In the other 30%, he will have x.
What is the best course grade your friend can earn?
This will happen if he earns 100% = 1 on the final test. So
The best course grade your friend can earn is 0.867 = 86.7%.
What is the minimum score would your friend would need on the final to earn a 75% for the course?
This is x, when the grade is 0.75. So
The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.
