Amass weighing 4 lb stretches a spring 1.5 in. the mass is given a positive displace-
ment of 2 in from its equilibrium position and released with no initial velocity. assuming that
there is no damping and that the mass is acted on by an external force of 2 cos 3t lb, formulate
the initial value problem describing the motion of the mass (do not solve the resulting system). it's the question about differential equations. provide specific solution.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
