According to the problem-solving strategies you've learned so far, once yo
have come up with a solution to the problem, you should return to the
equation and make sure your answer satisfies it.
True or false

true

Step-by-step explanation:

it is good to go back to the equation because maybe you placed a number wrongly or you did not understood the problem correctly

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.
