Answer:
150°
Step-by-step explanation:
To find the sum of all the interior angles in a regular polygon, us this formula, where n is the number of sides: (n-2)*180
(12-2)=10
10*180=1800
Now we have the sum of all the angles. But we aren't done yet! We have to divide this value by the number of sides to find the measure of one angle.
So,
1800/12=
150
Hope this helps!
Difference would be 1000x3.0 - 8.8x10000 = -85000
Scientific notation would be 8.5x10^-4
I know this is really late but the answer is y=-1/4x
Is it 89 ? Wouldn’t you just add them up from the starting point ?
Here, you have to foil the equation.
Distribute 4x to all sides, then distribute the -3 to all sides. Next, combine like terms. If you do this, your answer will be
