Question

pls explain me as soon anyone can

Answer 1

$x + y + z = 180$
Because they are collinear!
$y = 5x$
$z = 4x$
So,
$x + y + z = 180$
$x + 4x + 5x = 180$
$10x = 180$
$x = 18$
So the angle is 18°
HOPE IT HELPS PLZ MARK AS BRAINLIEST!!

Answer 2

$\frac{y}{x} = 5 \\ y = 5x \\ \\ \frac{z}{x} = 4 \\ z = 4x \\ x + y + z = 180 \\ x + 5x + 4x = 180 \\ 10x = 180 \\ x = \frac{180}{10} = 18answer$
