Whoever answer this question I will mark brainliest pls I need help 1.Given that ∆DEF ≅ ∆ZXY,
and
. Find 2.An iron rod 5m long is placed against the wall in such a way that the foot
of the rod is 3m away from the wall. Find how high the top of the iron rod
reaches in the wall?
3.Name the triangle in which two altitudes of the triangle are two of its
sides.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

sorry not knowing about that
