if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is
so the answer will be
they each measures 144 degrees
good luck
You pay attention in class
Hi there!
81x - 122 = 22
Add 122 to both sides
81x = 144
Divide 81 from both sides
x = 144/81
Simplify
x = 16/9 or 1.78
Hope this helped!
To solve this you'll want to set up a system of equations.
Since there were 1470 points scored total, and 470 of them were from 1 point baskets, that means 1470-470 = 1000 points were scored by 2 and 3 point baskets. Assuming x = the number of 2 point baskets scored and y = the number of 3 point baskets scored, that gives us an equation of 2x + 3y = 1000.
We also know that there were a total of 440 2 or 3 point baskets scored. Using x and y as defined before, we get an equation of x + y = 440.
To solve this, we can use substitution. Let's solve for x in terms of y for the second equation.
So x + y = 440. If we subtract y from both sides, we get x = 440 - y. Now we substitute 440 - y for x in the first equation.
2*(440-y) + 3y = 1000. Now we simply solve the equation.
880 - 2y + 3y = 1000.
880 + y = 1000.
y = 120.
So 120 of the baskets scored were 3 point baskets.
If we want to solve for x, we can substitute in the known value of y to the first equation
x + 120 = 440.
x = 320.
So 320 of the baskets scored were 2 point baskets.
