Question

find the angle X= ?​

Answer 1

Step-by-step explanation:

$< 1 = 70$

$< 2 =60$

$< 3 = 10$

$< 4 = 20$

$the \: sum \: of \: all \: angle \: is \: = 160$

$we \: know \: the \: sum \: of \: all \: angle \: of \: \\ traingle \: is \: = 180$

$so = 180 - 160 = 20$

$the \: value \: of \: x \: is \: = 20$
