Step-by-step explanation:
If it costs $60 for 200 minutes you can do $60 divided by 200 to find how much money it costs per minute which equals .3 or 3 cents a minute. so if you have 1272 minutes you can multiply that by .3 and it equals $381.60
Answer:
Option A is correct
True, ΔABC and ΔDEF must be congruent.
Explanation:
LA theorem or Postulates states that given two right triangles, where one acute angle and a leg of one of the triangles are congruent to an angle and a leg of the other triangle, then the two triangles are congruent.
In ΔABC and ΔDEF
AB = DE [Leg] [Given in the figure]
[Given]
[Acute angle] [Given in the figure]
Then, by the LA theorem or Postulates;
therefore, ΔABC
ΔDEF .
