Algebraically solve the following system of equations there are two variables that can be readily elicited but your answers will be the same no matter which you eliminate first

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

The formula for the volume of a right square pyramid is given below, where a is the side length of the base and h is the height.

One angle of a linear pair is 10 more than two-thirds the other angle. find the measure of both angles.
