Starting at home, umaima traveled uphill to the gift store for 45 minutes at just 8 mph. she then traveled back home along the same path downhill at a speed of 24 mph. what is her average speed for the entire trip from home to the gift store and back?

16 mph

Step-by-step explanation:

To find the average, you add up all the relevant numbers and then divide by how many numbers you have. In this case, it would be (8+24)/2. That equals 16, so the answer is 16 mph.

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
