The question is incomplete, however, the correct question is attached

in the image format:

Answer:

B. 171 N

Explanation:

The equation of the forces along the

Horizontal direction:


T_(2) cos62^(0) = T_(1) cos20^(0)...... 1

Verticalb direction:


T_(1) sin20^(0) = T_(2) sin62^(0) = W . . . 2

Where W = 180 N is the weight of the box.

From equation (1),


= T_(1) =T_(2) (cos62^(0))/( cos20^(0))

Substituting into equation (2),


(T_(2) (cos62^(0))/( cos20^(0)))
sin20^(0) = T_(2) sin62^(0)

=
T = (W)/(cos62x^(0) tan20x^(0)+sin62x^(0) )

=117 N

Thus, the correct answer is option B. 117 N
