Answer:
The resultant force magnitude is 129.90 pounds at angle of 60°
Step-by-step explanation:
Two given forces and resultant force form right triangle. The first force (150 pounds) is hypotenuse, the second force ( 75 pounds) and resultant force are right sides of the right triangle.
Then we can write pythagorin theorem
R= √150∧2 - 75∧2 = √ 22500-5625 = √16875 = 129.90
Good luck!!!
