Answer 2

Answer:

$\red {Value \:of \: a }\green {= 5}$

Step-by-step explanation:

$Given \: x = 3a ---(1) \\y = 5x\:---(2)\\z = 6x\:---(3)$

$2x+2y+2z = 360$

\* Sum of the angles around the point *\

$2(x+y+z) = 360$

$\implies x + y + z = 180\degree$

$\implies 3a+5x+6x = 180$

[ From (1), (2) and (3) ]

$\implies 3a + 11x = 180$

$\implies 3a + 11\times 3a = 180\: [ From (1) ]$

$\implies 3a + 33a = 180$

$\implies 36a = 180$

$\implies a = \frac{180}{36}$

$\implies a = 5$

Therefore.,

$\red {Value \:of \: a }\green {= 5}$
