Suppose that an object is attached to a coiled spring. It is pulled down a distance of 8 cm from is equilibrium position and then released. It takes 1/3 second to complete one oscillation. Find the
position of the object after 1/2 second.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
