Stefan said he had done an experiment similar to the jumping jack exercise. He had collected data on the number of deep knee bends a person could do in 2 minutes. The graph below shows his data. Describe in detail how the number of deep knee bends changes as time increases. *

answer:

what is your question that you ask

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.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
