Answer: Area of ΔABC is 2.25x the area of ΔDEF.
Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as
with a as side of the triangle.
Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:
a₁ = 1.2a
Then, its area is
Triangle DEF is 20% smaller than the original, which means its side is:
a₂ = 0.8a
So, area is
Now, comparing areas:
2.25
<u>The area of ΔABC is </u><u>2.25x</u><u> greater than the area of ΔDEF.</u>
Answer:
45.2°
Step-by-step explanation:
a = 14
b = 11
c = 10
The Law of Cosines is given as:
arccos (a²+b²﹣c²/2ab)
In this above question, to find m
= arccos(11²+14²﹣10²/2·11·14)
= 45.20717°
Approximately = 45.2°
Option d is the correct answer
