The ratio of the area of ∆ABC to the area of ∆DEF is; 1:100.
<h3>What is the ratio of the area of ∆ABC to the area of ∆DEF?</h3>
Since, a major criterion for similarity and congruence of triangles is that the ratio of corresponding sides are equal.
On this note, since the task content suggest that the ratio of the perimeters is; 1:10, it follows from conventional mathematics that the ratio of their areas is given as; 1²:10²; 1:100.

Well flat means open so 180°
180° - 50° = 130° is the answer
(12(18))+(13(13))= 216ft squared +169 feet squared = 385 ft squared
385feet squared ($3.50)=$1,347.50
12-5=7
21-12=9
x-21=11
21+11=32
x=32
Answer:
A
Step-by-step explanation:
Both angles together are supplementary, or they add up to 180 degrees.
(3x+12)+x=180 degrees
