Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))

pythagorean theorem=a squared + b squared =c squared

where c is the hypotenus(the longest part)

Step-by-step explanation:

16 squared = 8 squared +

16 ×16=256=8×8=64 + y

256_64=192

sq. root of 192=13.85

y=180_90=90

90÷2=45

y=45

z=45

x=13.85cm

hope you understand

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.
