Theo was asked to find the measure of x in the following polygon.
A polygon has angles 63 degrees, 63 degrees, x, and x.
Theo’s work is shown below.
Steps
Theo’s Work
Step 1
(n minus 2) 180 degrees = (4 minus 2) 180 degrees
Step 2
2 (180 degrees) = 360 degrees
Step 3
63 degrees + 63 degrees + x degrees = 360 degrees
x = 234 degrees
Where, if at all, did Theo first make a mistake finding the measure of x?
step 1
step 2
step 3
Theo did not make a mistake.

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
