Which postulate can be used to prove that the triangles are congruent?

t is the SAS postulate the side angle side because they both have the 90 degree angle and the sides are the same coming of of the 90

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
