Two borders opposite each other are 12 feet in length and 1 foot wide. There are 2 walls in between that are 10 feet long and 1 foot wide. The total number of feet used is 10 + 10 + 12 + 12 = 44 feet of brickwork.

The number of bags needed = 44/9 = 4 8/9 = 4.9 bags. <<<<< Answer rounded to the nearest tenth.

In practical terms, you would best buy 5 bags. You sure won't have much left.

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

central angle of a triangle has the same measure as its intercepted arc.
