Question

Find the missing part. Find Px

Answer 1

Px = missing length
xy = 3
Py = 6
these are the 3 sides of a right triangle; let's use the Pythagorean theorem to find Px
(Px)² + 3² = 6²  subtract 3² from both sides
(Px)² = 36 - 9 simplify the right
(Px)² = 27 take the square root of both sides
Px = $\sqrt{27}$
Px = $3 \sqrt{3}$
