For this first Pause-Problem, I want you to design three (brief!) studies (they can all be variations on the same idea). Make sure to note the independent and dependent variables for all

One should use an independent three group design
One should use a matched OR natural set design
One should use a repeated measures design

a 270° rotation about point p says on e d g e n u it y (had to space it out because it says it's a misspelling so i couldn't submit it

i got 10.28 but that rounds up to 10.3

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.
