x= 30 degrees
first, subtract 3 from 4 and you get 2sinx=1
then, divide both sides by 2 to get sinx=1/2
by using a 30, 60, 90 triangle you can see that 1 is the side opposite theta and
2 is the hypotenuse
therefore, your answer is 30

It has two equal solutions of 2
2 this Domo
2*sin^2(x) - 5*sin(x) + 2 = 0 is a quadratic equation in sin(x).therefore,{2*sin(x) - 1}*{sin(x) - 2)} = 0=> sin(x) = 1/2 or sin(x) = 2The second solution is rejected since sin(x) cannot exceed 1.The principal solution is x = arcsin(1/2) = pi/6 radians. Additional or alternative solutions will depend on the domain for x - which has not been given.
x = 2 and x = -5
It is a quadratic equation that has 2 solutions
