The grounds crew needs to mow the football field before their next game. Mr. Comb can mow the field in 5 hours, and Mr. Ramsey can mow the same
field in 4.5 hours. If they worked together, how long would it take for both
of them to mow the field if they worked together?
Round your answer to the nearest minute.

use formula for the circle a=3.14

step-by-step explanation:

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
