Question 5. Abob of a pendulum swings through an arc of 50 cm on its first swing. Each successive swing is 90% of the
length of the pervious swing. Find the total distance the bob travels before coming to rest​

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
