Given: ∠AOC and ∠BOC are complementary. m∠AOC=m∠BOC+30°. Find: m∠AOC and m∠BOC Statement Reason
1. m∠AOC+m∠ = 1.
2. m∠ + +m∠BOC=90° 2. Substitution
3. m∠BOC = 3. Algebra
4. m∠AOC = 4. Algebra

Statement Reason

1. m∠AOC+m∠COB= 90° 1. complementary angles

2. m∠30° + BOC+m∠BOC=90° 2. Substitution

3. m∠BOC = 30° 3. Algebra

4. m∠AOC = 60° 4. Algebra

I think I got it

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
