Answer 1

Answer:

30°

Step-by-step explanation:

Complementary angle = 90°

and 30° is the half of its complement that is 60°

Answer 2

$let \: \: \: 2 \: \: \: cmplementry \: \: \: angles \: \: \: be \\ \\ x \: \: \: nd \: \: \: y \\ \\ x = \frac{y}{2} \\ \\ x + y = 90 \\ \\ \frac{y}{2} + y = 90 \\ \\ y + 2y = 180 \\ \\ 3y = 180 \\ \\ y = \frac{180}{3} \\ \\ y = 60 \\ \\ x = \frac{y}{2} \\ \\ x = \frac{60}{2} \\ \\ x = 30$
