HELP! A couch is on a ramp that is inclined 27° to the horizontal, as shown. To prevent the couch from sliding, a force Q of magnitude 220N is required. The figure is not drawn to scale. Complete the following. Do not round any intermediate computations, and round your answers to the nearest hundredth. (a)Find the magnitude of the force C of the couch against the ramp.
N
(b)Find the weight of the couch, represented by force G.
N

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.
