Use the formula (n - 2) * 180 to find the sum of the interior measures of a polygon.
n stands for the number of sides that the polygon has, so substitute 10 for n since a decagon has 10 sides.
(10 - 2) * 180, start by solving inside the parentheses and subtracting 10 and 2.
(8) * 180, multiply.
B. 1,440 is your answer.
Answer:
-3 , 6
Step-by-step explanation:
You don’t need to go to 2 m because all values are between 0 and 1. So I’d probably say b, from 0 to 1 with intervals of .1.
3a-5=-14
+5 +5
3a=-9
/3 /3
a=-3
