5x+3x+6x=180

14x=180

x=180÷14

find x then find 6x your answer will be out

Answer 2

Step-by-step explanation:

$let \: the \: angles \: are5x \: 3x \: 7x \\ 5x + 3x + 7x = 180 \\ 15x = 180 \\ x = 12 \\ so \: the \: largest \: angle \: is7 \times 12 = 84$

so your answer is D)none of these

hope it helps you
