DECA=10, decagon = 10 sides.
since each side is 1.8 long, all 10 sides will be 10*1.8 or 18 units long, so that'd be the perimeter then,
10 mm = 1 cm
100mm = 10 cm
800 mm = 80 cm
816 mm = 81.6 cm
It’s hard to tell due to no labels, but these are your angles due to the equal angles theorem and a few other theorems. Hopefully with this image you can hopefully find your answer. You may need to add angles together depending on what you are looking for. And possible even figure out what angle measure would make a (180 degree) triangle.

Answer:
Step-by-step explanation:
B) the stone hits the water within the first 2 seconds. Because the stone drops at the speed of 88 feet/second, and 88 x 2 is 176. but the bridge is only 135 feet tall.
so,
88 feet/second
176 feet/2 seconds
135 feet means that it reached the river within 2 seconds. it reached the river in 1.545 seconds
Answer:
1 16/25
Step-by-step explanation:
1 whole and remaining decimal 0.64
0.64 is 64/100 as a fraction which simplifies to 16/25
So as a whole number its 1 + 16/25 which is 1 16/25
