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.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
