In ΔDEF, M and N are the points on sides DE and DF respectively. MN is parallel to EF and MN : EF = 2: 5. If DE = 60 cm, then what is the length of ME ? |
48 cm 24 cm 54 cm 36 cm |
36 cm |
We know that the ratio of MN to EF is equal to the ratio of DM to DE and also equal to the ratio of DN to DN So DE = EF = 60 ME = 5x - 2x = 3x 5x = 60 x = 12 3x = ME = 36 |
