HELP ASAP IT'S AN EMERGENCY

Last option must be correct because you need to prove three things congruent to give a postulate.In which case you have two sides of each triangle that means it is incomplete.

thus last option is correct.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
