Step-by-step explanation:

ANSWER:

The sum of the measures of complementary angles is 90º.

(i) 20°

Complement = 90° − 20°

= 70°

(ii) 63°

Complement = 90° − 63°

= 27°

(iii) 57°

Complement = 90° − 57°

= 33°

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
