Use the given information to complete the proof. given:∠A and ∠B are supplementary angles. ∠B and ∠C are supplementary angles.
prove:∠A≅∠C
match the reason with the provided statements to complete the proof.

The answers are as follow

1. ∠a and ∠b are supplementary angles, ∠b and ∠c are supplementary angles: given

2. m∠a + m∠b = 180, m∠b + m∠c = 180 : definition of supplementary angles

3. m∠a + m∠b = m∠b + m∠c : substitution property of equality

4. m∠a = m∠c: subtraction property of equality

5. ∠a ≅ ∠c: if two angles have the same measure, then they are congruent.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

2/5
