Two airplanes leave an airport at the same time. One airplane travels at 400 km/h and the other at 525 km/h. After 2 hours, the planes are 900 km apart. Determine the angle between their paths. Draw a diagram to help with your solution. Hint: distance = (speed)(time) (This is trigonometry)

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.
