the formula for the area of a trapezoid is a=1/2h(b1+b2). Which equations are equivalent to the formula? h=24/b1+b2, b1=24/h-b2

What is the point-slope equation of a line with slope -5 that contains the point (6,3)

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

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
