The larger of two supplementary angles exceeds the smaller by 20 degrees. Find the angles. |
|
Answer» let the two angle be /x and /yaccording to given condition-/x+/y = 180 ----(1)/x = /y + 18 -----(2)substituting the value of (2) in (1)(1) - /x+/y = 180- (/y+18)+/y = 180- 2/y+ 18 = 180-2/y = 162-/y= 81substituting the value of y in (2)/x=/y+18/x=81+18/x=99 Larger angle will be 110 degrees n the other smaller angle be 180 -110 i.s 70 degrees.Hope u found it helpfull ? Sorry by mistake jaldi send ho gaya X + X+20 = 180......... 2x+20==180.......2x==180+20==160............ X==160/2=80 |
