harina [27]

Answer:

2820.36 feet

Step-by-step explanation:

First we need to find the length of the outer corridor, and we do that by finding the length of the circunference with a radius of 25 feet:

C = 2 * pi * r = 2 * pi * 25 = 157.08 feet

Now, as Heather walks the outer corridor 17 times and the length of 6 spoke aisles (the radius of the circunference), we have that the total distance she walks is:

Distance = 17 * 157.08 + 6 * 25 = 2820.36 feet

2 angles that are complementary. One angle is 4 degrees less than three times the other angle. Find the measures of the angles.
77julia77 [94]
Complementary angles add to 90o

the other angle = x
the first angle = 3x - 4

x + 3x - 4 = 90
4x - 4 = 90
4x = 94
x = 94/4
x = 23.5

the first angle = 3*23.5 - 4 = 66.5
