A property and casualty insurance company categorizes its policyholders into three groups: low risk, medium risk, or high risk. 25% of the policyholders are low risk and 30% are high risk. The high risk policyholders are three times as likely as medium risk policyholders to file an insurance claim and the medium risk policyholders are twice as likely as the low risk policyholders to file an insurance claim. Determine the proportion of the insurance claims filed by medium risk policyholders.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
