WebDec 8, 2014 · 1. Draw a right-angled triangle with angle A, opposite side 2 and adjacent side 5, so that tan A = 2 5. You should be able to read off the triangle that sin A = 2 29 and cos A = 5 29. If B is in the third quadrant then B − π is in the first quadrant and cos ( B − π) = − cos B = 2 3. Draw another triangle in order to find sin ( B − π). WebNov 23, 2009 · Mark44 said: If you set sinAcosB + sinBcosA = sinA + sinB, this will be true if cosB = 1 and cosA = 1, which means that A and B can be 0, pi, 2pi, etc. Any integer multiple of pi works. It's much harder to find a solution for cos (A + B) = cosA + cosB, since cos (A + B) = cosAcosB - sinAsinB. I think he means angles besides those (which are ...

WebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the complementary angle. We can then set up an equation with just the arguments: 50 - x + 3x + 10 = 90. 2x + 60 = 90. 2x = 30. x = 15. 3 comments.
