Two angles whose measures are a & b are suchthat 2a - 3b = 60° then 5

1.	Two angles whose measures are a & b are suchthat 2a - 3b = 60° then 5b =?, if they form a linearpair(1) 120°(2) 300°(3) 60°(4) of these
Answer» 2a - 3b = 60. (given)..............ia + b = 180. (linear pair)..........ii multiplying equation ii by 2 and substracting the equations we get -5b = -120 Multiplying by (-1) 5b = 120°🏆🏆🏆 (1) 120° is the best answer 120 multiple efyhgfxdyjh dogfighting ffyijjcdyijxx cgjkjcv it's answer is 120 this is a right answer

Answer»

2a - 3b = 60. (given)..............ia + b = 180. (linear pair)..........ii

multiplying equation ii by 2 and substracting the equations we get

-5b = -120 Multiplying by (-1)

5b = 120°🏆🏆🏆

(1) 120° is the best answer
