Answer:
90 inches
Step-by-step explanation:
The perimeter of the inscribed triangle is 1/2 that of the enclosing triangle. So, the total of perimeters is ...
(3·16 in)(1 +1/2 +1/4 +1/8) = (48 in)(15/8) = 90 inches
All we have to do is divide the distance of the old sidewalk by 3.14:
65 / 3.14 ≈ 20.7006
That means that, rounded to the nearest meter, the new sidewalk is:
21 meters long!
Answer:
13 grados es igual a 0.226893 radianes
Step-by-step explanation:
These are vertical angles and vertical angles are congruent. So you set them equal to each other
5x+12=6x-10
-5x -5x
12= x-10
+10 +10
X=22
