Look at the figure below: Triangle ABC is a right triangle with an angle ABC equal to 90 degrees. The length of AC is 7 units and the length of AB is 5 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?

6
8.5
7
9.8

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

answer:

your answer is: c. 196 7/8 in^3.
