Two rules for creating a pattern are given below. Rule 1: Multiply x by 5 to get y.
Rule 2: Add 12 to 3 to get y.
Which ordered pair, (2, y), works for both rules?
Pls help?

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

Measure a and b and find their sum. how are the angles related?
