Pravat used parking cones to set up a rectangular football field in the park. However, when his friend Brian arrived at the park, he told Pravat that they should dilate the field by ¼. Which best describes the changes that Brendan and Poorav will make to the side lengths and interior angles of the football field?

a. Both the side lengths and the interior angles will change.
b. The interior angles will change, but the side lengths will remain the same.
c. The interior angles will remain the same, but the side lengths will change.
d. Neither interior angles nor side lengths will change.

14

step-by-step explanation:

14 x 3 = 42

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.
