Abby needs to find the area of the shape shown below, a shape she is not too familiar with. She knows that she can dissect the polygon into more familiar shapes, so she begins to dissect it. When she does this, she realizes that m∠FAE is 30°. Since she knows that FA = 10 cm and AB = 5 cm, she now can find it's total area. What is the total area? Round answer to the nearest whole number. Do not round until the final answer.

answer:   rlly

step-by-step explanation:

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.

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
