Two airplanes are approaching the airport tower at the same altitude. radar shows that plane a is 20 miles due east of the tower and that plane b is 22 miles at 15° north of east. (see the drawing provided above).
how far apart are the two planes? round to the nearest hundredths.
the right system of equations to describe the situation would
be on the form:
x1 = 8000 + y1*t
x2 = 8000 + y2*t
where x1 and x2 represents the total money of imogene and her
friend respectively at the end of t years.
now for the value of amount earned, y1 and y2:
i think is sss
sss similarity theorem. by definition, two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional. sss similarity theorem: if all three pairs of corresponding sides of two triangles are proportional, then the two triangles are similar.
