Expert Answer

Step 1

Given:

Tension in both cables (T) = 1000 lb

angle between both cables θ = 50o

Step 2

vector diagram will be,

the vectors are rearranged in manner so that the end of one vector meets tail of another vector.

Step 3

Angle between both vector will be = 180-50 = 130.

With the help of following cosine formula magnitude of c can be calculated.
