Answer: 18
Step-by-step explanation:
2 degrees per hour
9 hours
1hour = 2 degrees
2hours= 4 degrees
3hr= 6 degrees
4hr= 8 degrees
5hr=10 degrees
6hr= 12 degrees
7hr= 14 degrees
8hr= 16 degrees
9hr= 18 degrees
So you are basically doing 2x9 to get your answer

Straight Angle-A straight angle is 180 degrees. This is a straight angle.
Step-by-step explanation:
180 is a straight angle and 90 is a Right angle
Answer:
r≈1.34 and the volume is 10
Step-by-step explanation:


To solve for the area of a triangle, we multiply the length and height, then divide that by two. L = 10. H = 7.



To solve for the perimeter, or edges, of the triangle, we need to use the Pythagorean Theorem: a² + b² = c² to solve for the third side. We already know two measures: 10 and 7. Now we need to square them, add them together to get c², then take the root of that number.

We cannot simplify √149, so we either leave it, or round it.

This is rounded to the nearest 10,000.

Now that we have the measure of the longest side, we can add all three sides together to get the perimeter of the triangle.
