Question

QUESTION REVIEWING 1 OF 4 ANSWER I DO 6.00 m when vector à is added to vector B, the resultant is vector R such that A = Ā+ B This resultant vector has components R, A, B, and Ry-Ay+ B, What is the magnitude of the resultant vector R-A+Bwhen you add A and B? 3.03 m THE CORRECT ANSWER A (3.60 m) 2.34 m 1.20 m 70.0° 1.33 m 30.0° B (2.4 m) YOUR ANSWER I DON'T KNOW YET WHAT YOU NEED TO KNOW When you add A and B, the magnitude of the resultant vector is 2.34 m. The x-component of R is R, -A, +B, (3.60m) cos70 + (2.4m) cos 210°- -0.850 m. The y-component of R is R, A, B, (3.60m) sin 70+(2.4m) sin 210° - 2.18 m. R and Ry form the base and height of a right triangle whose hypotenuse is length R According to the Pythagorean theoremVO.Simp + (2.1bm -2.34 m hypotenuse is length R. According to the Pythagorean theorem, - 2.34 m.

I am confused why for the y component calculations that 210 was used for angle measure instead of 30. Could someone please explain this to me?
