Determine whether the triangles are similar. If so, name the postulate or<br> theorem you used.
Mice21 [21]

Answer:

Yes, AA~

Step-by-step explanation:

because 2 of the angles are the same (90 and 52) they have to be the same. The triangle on the right is known to be 90 degrees because 52+38 is 90 and 180-90 is 90 and a triangle has to add up to 180 degrees

A car passes a landmark traveling at a constant rate of 55 kilometers per hour. One hour later, a second car passes the same lan
yarga [219]
Recall your d = rt, distance = rate * time

one car is going at 55kph, at say hmmm "t" time
the second car zooms by at 75kph, an hour later, thus " t + 1 "

notice, overtaking the 1st car, simply means, the second car comes from behind approaches the first car from behind and "gets there", at that very second, both cars have travelled a distance, say "d"

if the first car travelled "d" kilometers
for the second car to "get there" has to had travelled "d" distance as well

\bf \begin{array}{lccclll}&#10;&distance&rate&time\\&#10;&-----&-----&-----\\&#10;\textit{first car}&d&55&t\\&#10;\textit{second car}&d&75&t+1&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;d=55t\\&#10;d=75(t+1)\\&#10;-------\\&#10;55t=75(t+1)&#10;\end{cases}

solve for "t"
