Diane and douglas both drive at an average rate of 50 miles per hour. diane travels 20 miles further than douglas. diane drives for at least 2 hours, but no more than 4 hours. which statement correctly describes the range of distances that douglas may drive? a.) douglas drives at least 80 miles, but no more than 180 miles. b.) douglas drives more than 80 miles, but less than 180 miles. c.) douglas drives more than 120 miles, but less than 220 miles. d.) douglas drives at least 120 miles, but no more ham 220 miles

B, i am in 12th grade so this should be the right answer.

I wish I could give a explaniation other than I took the test, but I did take the test and the answer is

A.) Douglas drives at least 80 miles, but no more than 180 miles.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
