Determine if the two triangles are congruent. if they are, how you know.

not enough info

Step-by-step explanation:

you know that 2 angles are congruent. the third angle is right so they are congruent. so you have 3 angles that are congruent. AAA doesn't prove triangle congruence because the sides could be any length and still have congruent angles.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
