Given: ∠a is a straight angle. ∠b is a straight angle. prove: ∠a≅∠b it is given that ∠a and ∠b are straight angles. this means that because of using m∠a=m∠b . finally, ∠a≅∠b

Given: ∠A is a straight angle. ∠B is a straight angle.

We need to Prove: ∠A≅∠B.

We know straight angles are of measure 180°.

So, ∠A and <B both would be of 180°.

It is given that ∠A and ∠B are straight angles. This means that both angles are of 180° because of the the definition of straight angles. Using the definition of equality, m∠A=m∠B . Finally, ∠A≅∠B by definition of congruent.

The total inches of the ribbon is 1080 inches, so you can cut 270 in 4 inch pieces

Step-by-step explanation:

First I multiply 6 feet with 15 to get 90. Then I convert the 90 feet into inches which is 1080. So by dividing 1080 by 4, you will get 270 as the final answer

Hope this helped
