Question 7 (4 points) Carmen is planning to invest $200 in a retirement account at the end of each month for the next 20 years. The account is earning 3.15%
Interest, compounded annually. He used the following formula and variables to solve for the future value of the account after 20 years,
FVOA - C. (1+)*1
FVOA - Future Value of an Ordinary Annuity
C = 200
n=1
20
1 = 0.0315
He found that the future value of this account will be 55456.83. Is Carmen's solution correct? If not, explain what he did wrong and provide the
correct solution (4 points)

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
