Exercise 2
skylar is answering the following math problem:
of the investment was $75.00. what is the current
the value of an investment decreased by 10%. the original amount of the investment
alue of the investment?
a. skylar said 10% of $75.00 is $7.50, and since the investment decreased
$7.50 from $75.00 to arrive at the final answer of 56750. create one aigeuran
arrive at the final answer of $67.50. solve the equation to prove it res
to explain your thought process to the class.
creased by that amount, you have to subtract
one algebraic equation that can be used to
to prove it results in an answer of $67.50. be prepare

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

1/2*qr*rs
