Answer:
The interior angle measure of a convex decagon is 144.
Step-by-step explanation:
The sum of the interior angle formula for a convex polygon is (n-2)180
where n is the number of sides.
A decagon has 10 sides.
10-2 = 8
8 times 180 = 1440
A decagon has 10 sides-10 angles.
To find the measure of each angle divide by 10.
1440/10=144
The interior angle measure of a convex decagon is 144.
Answer:
-8/45
Step-by-step explanation:
- Change 3 3/4 into an improper fraction = 4/15
- To change it into multiplication put the dominator on the top = -2/3 × 4/15
- Then multiply it.
- = -8/45
