55 degrees. If you add the other three angles together you get 305. Considering that a circle is 360 degrees, you would subtract those two and get 55.
Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense
Answer: 301.44
Explanation:
V = πr^2•h
3.14•4^2 • 6
2,000 + 400 + 70 would equal 2,470.
The correct way to write it would be 2,000 + 400 + 7
