Answer 2

Answer :-

$angle \: \: 1 = (x - 4)\\ angle \: \:2 = (x - 20)\\ angle \: \:3 = ( \frac{1}{2}x \times 10) = (5x) \\ \: \: \: \: \: \: according \: \: to \: \: angle \: \: sum \\ property \\ angle 1 + angle 2 + angle 3 = 180 \\ (x - 4) + (x - 20) + ( 5x) = 180 \\ x - 4 + x - 20 + 5x= 180 \\ x + x + 5x - 4 - 20 = 180 \\ 2x + 5x - 24 = 180 \\7x = 180 + 24 \\ 7x = 204 \\ x = \frac{204}{7}$
