2x + 3y = 03x + 4y = 5( By substitution method ) |
|
Answer» Taking the LCM of 2 and 3 to eliminate x :- 3(2x + 3y = 0) 2(3x +4y = 5) Or 6x + 9y = 0.......... eq.3 -2(3x+4y =5).... eq.4 Subtracting 4th eq from the 3RD gives :- y = - 10 Now substituting y in the 1st eq :- 2x + 3(-10) = 0 2x - 30 = 0 x = 30/2 Or x = 15 Therefore, the values of x and y are 15 and - 10 respectively. P. S. - I just realized it has to be DONE using substitution. Apologies! (You've GOT both the methods, you lucky PAL!) |

Prove that the bisectors of a pair of vertically opposite angles are in the same straight line. |
|
Answer» AB and CD are straight LINES intersecting at O. OX the bisector of ANGLES AOC and OY is the OY is the bisector of BOD.OY is the bisector of BOD.∴ 1 = 6 (1)OX is the bisector of AOC.∴ 3 = 4 (2)2 = 5 (3) (Vertically opposite angles)We KNOW that, the sum of the angles formed at a point is 360ï½.∴ 1 + 2 + 3 + 4 + 5 + 6 = 360ï½⇒ 1 + 2 + 3 + 3 + 2 + 1 = 360ï½ (Using (1), (2) and (3))⇒ 21 + 22 + 23 = 360ï½⇒ 2(1 + 2 + 3) = 360ï½⇒ DOY + AOD + AOX = 180ï½⇒ XOY = 180ï½∴ The bisectors of pair of vertically opposite angles are on the same straight line.HOPE IT HELPS..! |
