Answer» Given,∠POY = 90° & a : b = 2 : 3 A/Q ∠POY+∠POX =180° [By linear pair axiom] ∠POY+ a + b = 180°⇒90° + a + b = 180°⇒a + b = 90° Let a = 2x & b= 3x2x + 3x = 90°⇒5x = 90°⇒x = 18° ∴ a = 2×18° = 36° b = 3×18° = 54° Now, OX is a ray on the line MON. ∠XOM + ∠XON=180°b + c = 180° (by Linear Pair axiom)⇒54° + c = 180°⇒c = 126° The value of c =126° 126° is the right ans of this question the correct answer is 126° of the following right answer is 126° of the following question the correct answer is 126° the value of c is 126 v zgdh uvyduudhfch udjcuj jvyvjd p is 126 i think that so please like me the value of c = 126° let a=2xlet b=3x 2x+3x+90=180(by linear pair)5x=180-905x=90x=90÷5x=18on line MN there is c and bb=3×18=54b+c=18054+c=180c=180-54c=126 126 is the right answer of following questions c=126° a x + b x is equal to 90 if you take two asex then 5 x is equal to 90 then b equal to 54 then b + C is equal to 180 after that C is equal to 126 c= 85 answer to the same wright a/b=2/3i.e. a=2x = 2×18° =36°and b=3x = 3×18°= 54°so to find c for straight line MON b + c = 180°54 + c = 180° c = 180° - 54°c = 126° ans. the value of c is 126 the value of c is = 126 degree.please like as best Answer of the above question is 126° the value of c is 126 degree .please like as best for the points a+90°=ca=2so,90°+2=92°c=90° A:B=2:3 let us imagine that 2x=a A.T.PanglePOX+anglePOY=180A+B=180-902X+3X=905X=90X=18 DEGREE 126 is a measure of angle c my answer is126' and it's correct a=36°,b=54°c=180-54=126° leta+b=90 a=2x b=3x2x+3x=905x=90x=90/5x=18^2*=2×18=36=a3*=3×18=54=bb+c=180^54+c=180c=180-54c=126^ Given,∠POY=90°∠POY=90°anda:b=2:3a:b=2:3.  Let, common ratio ofaandbbex. a=2x,b=3xa=2x,b=3x By property of Linear pair of Angles, ∠XOM+∠POM+∠POY=180°3x+2x+90°=180°5x=90°x=18°∠XOM+∠POM+∠POY=180°3x+2x+90°=180°5x=90°x=18° Now, a=2x=2×18=36°a=2x=2×18=36° By Vertically Opposite Angles, ∠XON=∠MOY=a+90°=36°+90°=126°∠XON=∠MOY=a+90°=36°+90°=126° Thus,c=126°c=126°. therefore angle at c is 126degree what are your responsibility option a is correct hi I'm arundfhiijgfffghjijjyhhuuuuiiiiiuyyytyyuuuu XY and MN are linesanglePOY=90°a:b=2:3from the figure a+b=90°sum of the terms of the ratio a:b=2+3=5therefore b=3/5×90=54°from the figure b+c=180°(linear pair of angles)54+c=180°c=180°-54=126° C=126° is the correct answer C is 120 degree as it a is 36 degree and b is 54 degree a:b=2:3angle poy=90degrees=2x+3x+90=180=5x=90x=18=2x=2(18) =36=3x=3(18) =54angle poy=90 degreespoy+54=180angle poy=180-54 =126a=36b=54c=126 now angle c is 126 bcoz 180 -54.i.e angle b=126° 144 is right answer.. |
