While Brandon is taking lessons on the French horn, he must also learn to tune his horn. Brandon has used his calculator and motion detector to collect the data while he plays
what he thinks is middle A, which has a frequency of 440 Hz. The graph produced from the
note he played shows a period of 0.00253 cycles per second. What is the actual frequency
of his note rounded to the nearest whole number?

c.   x=2.4cm

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.
