Triangle def has been dilated to form triangle d'e'f'. what is the least amount of information needed to determine if the two triangles are similar?
a) angle f=f', angle e=e', and segments ec and e'c' are congruent.
b) segment ec=e'c', segment df=d'f', and angles e and e' are congruent.
c) angles e and e' are congruent, and angles f and f' are congruent.
d) segments df and d'f' are congruent, and segments ef and e'f' are congruent.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
