Rosita had 17 subtraction problems and 28 multiplication problems. if she ca finish five problems in 20 minutes, how long will it take her to finish all the problems?

Step-by-step explanation:

total problems = 17+28=45

If she ca finish five problems in 20 minutes,

she take 45/5*20=180 minute = 3hour

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
