    For F2 - F1
    R² = F2² + F1² - 2.F1.F2.cos60
    = (20)² + (10)² - 2.10.20.½
    = 400 + 100 - 200
    = 300
    So R = 10√3
    2 Methods for solving for tan alpha:
    METHOD 1 (draw negative F1 and get say β in terms of -F1 normally, thus the angle between F2-F1 and -F1)
    tanβ = F2.sinθ / (F1 + F2.cosθ)
    = 20.sin120 / 10 + 20.cos120
    = 20.sin120 / 10 + 20.-½
    = 20.sin120 / 10 - 10
    = 20.sin120 / 0
    = ♾️
    This implies that β = 90
    Angle between F1 and -F1 = 180 = β + α and so α = 90
    METHOD 2: Derive an eq for subraction of vectors
    tanα = F2.sin(180-θ) / F1 + F2.cos(180-θ) [sin(180-θ) = sinθ]
    Thus, tanα = F2.sinθ / F1 + F2.(-cosθ) [cos(180-θ) = - cosθ]
    tanα = F2.sinθ / F1 - F2.cosθ
    Now substitute and get the answer
    tanα = 20.sin60 / 10 - 20.cos60
    = 20.sin60 / 10 - 20.½
    = 20.sin60 / 10 - 10
    = 20.sin60 / 0
    tanα = ♾️
    α = 90
    Another angle would be thus 120 - 90 = 30....
    So pls let me know which angle should be taken?? 🙏🙏
    Hope this helps...

    Lekin aap unse alag ho aur hume aap jaise hi teacher ki talash thi
    Hats off you sir for hardworking, not giving up attitude
