On a particular day, the wind added 4 miles per hour to jaime's rate when she was rowing with the wind and subtracted 4 miles per hour from her rate on her return trip. jaime found that in the same amount of time she could row 34 miles with the wind, she could go only 18 miles against the wind. what is her normal rowing speed with no wind?

recall your d = rt, distance = rate * time.

j = Jaime's rate

so with the wind her rate is j + 4, and without the wind her rate is j - 4, we also know that she can do with the wind 34 miles and against it 18 miles all within the same amount of time of t hours.

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
