Mr. Da Silva used 105m3 of water for the first half of 2002. In 2002, water rates for the domestic users for half a year were as follows:
$2.50 per cubic metre for the first 25m3
$2.00 per cubic metre for the next 50m3
$1.50 per cubic metre for amounts in excess of 75m3
5% discount on bills paid before July 7.
Calculate the amount Kyle paid for the half year, assuming that the bill was paid
before July 7.

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
