pls send the correct answer ...its urgent ​

Answer 1

Step-by-step explanation:

as we know sum of all angle of a triangle is 180°

$4x - 2 + 6x + 6 + 7x - 18 = 180$

$17x - 14 = 180$

$17x = 180 + 14$

$17x = 194$

$\frac{194}{17} = 11.4$

$x = 11.4$

$m qr = 7(11.4) - 18$

$= 61.8$

I hope it's clear
