Look at the figure below. http://learn.flvs.net/webdav/assessment_images/educator_geometry_v14/pool_Geom_3641_0300_Subtest_01_05/image0044e1c9dfb.jpg A four sided figure ABDC is shown with AB = BD = 20 cm. A line joins points B and C. The measure of angle ABC is 40 degrees and the measure of angle DBC is 47 degrees. The length of DC is 15 centimeters. Which conclusion is most likely correct about the figure? The length of side AC is equal to 10 cm. The length of side AC is equal to 15 cm. The length of side AC is equal to 35 cm. The length of side AC is equal to 20 cm.

hint - side opposite to larger angle is longer

ganeshie8 (ganeshie8):

in the pix 47 > 40 so, 15 > AC

ganeshie8 (ganeshie8):

its same as, AC < 15

ganeshie8 (ganeshie8):

check the given options - only one is less than 15
