Sheldon is four years older than his brother lee. togethet the boys are at most 26 years old. the inequality c+(c+4) is less or equal 26 can be used to determine the ages of boys. what does (c+4) represent? if lee is 5 years old how old is sheldon? if lee is 5years old what is the combine age of sheldon and lee? can lee be older than 11 years old?

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.
