(a) 2* = 16
(d) 7* = 493​

@ )2/16 = x = 8

b)493 / 7 = x= 70.42

Answer 2

$\huge{\red{\mathtt{\underline{Answer:}}}}$

$\mathtt{Let\:the\:first\:angle = 5x}$

$\mathtt{Let\:the\:second\:angle=6x}$

$\mathtt{Let\:the\:third\:angle=7x}$

$\mathtt{Sum\:of\:angles\:of\:triangle=180°}$

$\mathtt{5x+6x+7x=180°}$

$\mathtt{18x=180°}$

$\mathtt{x=\frac{180°}{18}}$

$\mathtt{x=10°}$

$\mathtt{The\:first\:angle = 5 \times 10° = 50°}$

$\mathtt{The\:second\:angle = 6\times 10° = 60°}$

$\mathtt{The\:third\:angle = 7\times 10° = 70°}$
