Answer:

straight angle

Step-by-step explanation:

it is 180 degree

Answer 2

$let \: y \: and \: x \: be \: two \: complmentary \\ angles. \\ x + y = 90°\\ y \: is \: half \: of \: x \: \: \: ie. \frac{x}{2}$

$we \: have\\ x + y = 90 \\ x + \frac{x}{2} = 90 \\ \frac{3x}{2} = 90 \\ 3x = 180$

$x = \frac{180}{3} = 60° \\ angle \: required \:is \: y = \frac{x}{2} = \frac{60}{2} \\ = 30°$
