Answer:
Length = 27.2
Width = 6.8
Step-by-step explanation:
P = L+L+W+W
68 = 4(L+L)+W+W
68 = 4(x+x)+x+x
68 = 4x+4x+x+x
68 = 10x
x = 6.8
L = 4x
L = 27.2
W = x
W = 6.8
68 = 27.2+27.2+6.8+6.8
68 = 68

Answer:

Step-by-step explanation:
In this cross sections problem, we can integrate from -r to +r (so that the integral covers the entire base of the solid).

The formatting for the integral did not let me put -r on the lower bound, so i replaced it with a, just know that a represents -r here.
Evaluating the integral gives use that it is equal to;

Answer:
72°
Step-by-step explanation:
The external angle E is half the difference of subtended arcs CG and DF.
E = (CG -DF)/2
2E = CG -DF . . . . . . multiply by 2
DF = CG -2E = 160° -2(44°) . . . . . add DF-2E to both sides; substitute values
arc DF = 72°
