The cost of the television was $200. The cost was increased by 10% and then decreased by 10%. What was the final price of the television? $176.00
$200.00
$198.00
$180.00

$198

Step-by-step explanation: its 198 because u times 200 by .10 u get 20 so u add 20 then u get 220 then u multiply 220 by .10 again and u get 22 then u subtract 22 from 220 and u get 198

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

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
