The answer is:
The second option, Denver received 21.3 inches of snow during the period from 1888 to 1889.
<h2>Why?</h2>To know how many inches of snow did Denver receive, we need to sum each the number of inches received per year from 1888 to 1889.
So, from the graph, we have:
For Nov '88, 3 inches.
For Dec '88, 0.8 inches.
For Jan '89, 5.5 inches.
For Feb '89, 8.4 inches.
For Mar '89, 3.6 inches.
Now, adding the number of inches for each month/year, we have:
Hence, we have that Denver received a total of 21.3 inches for the 1888-1889 year period.
Have a nice day!
Answer:
1. B (obtuse)
2. Obtuse
3. 20.92
Step-by-step explanation:
1.
We need to use the converse of the pythagorean theorem to solve this problem. Given that c is the longest side of a triangle, and a and b are the other two sides. The triangle is right triangle if
The triangle is acute triangle if
The triangle is obtuse triangle if
the longest side of this triangle is 47, so we check:
, and
Hence, c^2 is GREATER than a^2 + b^2, so the triangle is obtuse.
2. Using the points we showed above, we can again summarize:
- If
-- Right Triangle
- if
-- Acute Triangle
- if
-- Obtuse Triangle
This triangle's c (longest side) is 5. Let's check:
5^2 = 25, and
Hence, c^2 is GREATER than a^2 +b^2, so the triangle is obtuse.
3.
The side opposite of the 90 degree angle is the <em>"hypotenuse"</em>, that is x. The side opposite the 35 degree angle is <em>"opposite"</em> side.
The trigonometric ratio that related "opposite" side to "hypotenuse" side is SINE. So we can write:
Now, cross multiplying and solving:
