Please help, giving brainliest Look at the figure above:
Triangle ABC is a right triangle with angle ABC equal to 90 degrees. The length of AC is 7 units and the length of AB is 5 unit
What is the length, in units, of segment CD? (5 points)
Select one:
a. 6
b. 8.5
c. 7
d. 9.8

Length of CD = 9.8 units

Step-by-step explanation:

Given AB || CD

angles BAC = ACD ................alternate interior angles

Angles CBA = CAD = 90   (given)

=>

Triangles ABC and CAD are similar (AAA)

AB / AC = CA / CD   ................Similar triangles have corresponding sides proportional

5 / 7 = 7 / CD

CD = 7*7/5 = 49/5 = 9.8
