In fig., if AB।। CD, EF and y:z=3:7, find x. |
|
Answer» Considering LINE AB || EF angle x and Z are INTERIOR alternate angles and hence they are congruentTherefore; angle x is CONGRUENT to angle zTherefore RATIO of y:x will also be the same to y:z i.e 3:7so..... Let the common ratio be aso y=3a and z=7a3a+ 7a=180.....(consecutive interior angles are supplementary)10a=180a=18y=3×18=54x=7×18=126 |
