for the following right triangle, find the side length x. round your answer to the nearest hundredth.
oo explanation
to find a missing side length in a right triangle, we use the pythagorean theorem:
if the legs have lengths a and b and the hypotenuse has length c, then a + b

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
