  • Answer:

    36.87

    Step-by-step explanation:

    Sine rules says:

    . sin x = opposite / hypotenuse

    We just substitute in the values

    . sin x = 3 / 5

    . sin x = 0.6

    Now we use sin inverse to find the value of the angle

    . x = sin^-1(0.6) = 36.87

  • [tex]\sin \angle A = \dfrac{3}{5} \\\\\implies \angle A = \sin^{-1} \left( \dfrac 35 \right) = 36.87^{\circ}[/tex]
