A person is flying a kite to the full extend of its 200-ft-string. Using a protractor, they measure the angle of elevation the string makes with the
ground as 50°.
If the person flying the kite is holding the tether 5-feet above the ground, what is the
vertical height of the kite?

2.78 feet

Step-by-step explanation:

Rounded to the nearest hundredth.

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.
