Answer:
Below
Step-by-step explanation:
The components form a RIGHT triangle with legs = Horizontal comp and Vertical comp and hypotenuse = the force...
SO you can use the Pythagorean theorem
Hypotenuse ^2 = leg1^2 + leg2^2
140^2 = 75^2 + Horizontal^2
Horizontal^2 = 140^2 = 75^2 = 13975
Horizontal = 118.2 N
