The two vectors a and b in the figure have equal magnitude of 29 m and the angles are θ1 = 31° and θ2 = 105°. Find the x-component of their vector sum r. Find y-component sum. Magnitude of the vector sum? Find the angle that their vector sum r makes with the positive direction of the x-axis.

2. Relevant equations

3. The attempt at a solution

Ok i am confused as to why this won't work.

x = 29cos31 + 29cos105

y = 29sin31 + 29sin105

The second vector/magnitude points towards the y axis and the first one points away. i can not seem to insert a picture.
