x = 32°
The triangle has 2 equal sides and is therefore isosceles, thus the 2 base angles are also congruent.
The 2 base angles are of size x°
x =
=
= 32
3 feet width is added to both sides .
so the dimensions become 34 feet and 36feet
hence the fencing length required or the perimeter= 2(l+b)
= 2( 34+36)
= 2(70)
= 140feet fence
The answer is A.
USE PYTHAGOREAN THEOREM
3^2+6^2=c^2
9+36=c^2
45=c^2
c=3 sqrt5
<span>It costs 19.48, because $16,421.40 / 843 comes out to 19.479, and 19.479 rounds to 19.48. So the answer is B $19.48</span>
Answer:
DE = 55
Step-by-step explanation:
As you can see from the red marks showing that the lengths of each triangle are the same, it must also be true that E is equal to 55.
