Two forces with magnitudes of 150 and 100 pounds act on an object at angles of 40° and 170° respectively. find the direction and magnitude of the resultant force. round to two decimal places in all intermediate steps and in your final answer.

Resultant force =115.03 pounds

Direction of resultant force=81.8 degrees

Step-by-step explanation:

We are given that two forces

Let

Vertical component of force

Horizontal component =

Vertical component of second force

Horizontal component of force

Vertical component of  resultant force=96.45+17.4=113.85

Horizontal component of resultant force=114.9-98.5=16.4

Magnitude of resultant force ==115.03 pounds

Direction =

Direction of resultant vector force==81.8 degrees

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
