Find the result when 80 is decreased by 75%.

75% of 80=60

80-60=20

the result of a 75%(60) decreasue to 80 is 20

20

Step-by-step explanation:

If you multiply 20 times 4, you get 80! Which in turns means 20 is 25% of 80, therefore, the other 75% is taken out, resulting in that 20.

It was nice answering your question!

Thanks,

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.
