We need to subtract 1050 from 1280, which is 230, now we need to find what percentage 230 is of 1280, so that is 17.97%, so the percentage of decrease I think is 17.97%. Please give 5 stars if right :)
<span><span>−4−3×3+2</span><span><span>−4−9+2</span><span><span>−11</span><span>
The answer is -11.
Hope this helps :)</span></span></span></span>
We are asked in the problem to solve for x in the expression tan(x+π)+2sin(x+π) = 0. tan theta is equal to sin theta over cos theta. Hence, the expression results to tan (x+π) = sin (x+π) / cos (x+π) = -2sin (x+π). Thus, 1/cos (x+π) = -2. cos (x+π) = -1/2, cosine becomes negative in the third and fourth quadrants. cosine is 1/2 when the terminal angle is pi/3. x is equal to pi/3 then and 5 pi/6.
Answer:
x=74
Step-by-step explanation:
because those two angles you can assume are equal, and all you have to do is subtract 180 by 32 and divide 148 by 2 to get the other two parts of the triangle.
