Homework Statement
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.
Homework Equations
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.
