Question

find X Y and Z in each of the following figures​

Answer 1

X=Z=180-75
=105
And y+4 =13
Y=9

Answer 2

Answer:

$opposite \: angles \: are \: equal$

$75 + 75 + x + z = 360$

$angle \: x = angle \: z$

$150 + 2x = 360$

$2x = 210$

$x = 105$

$the \: angle \: of \: x \: \: is \: 105$

$the \: angle \: of \: z \: is \: 105$

$y + 4 = 13$

$y = 9$
