Answer:
sum of interior angles of the octagon is 1080 degree
Step-by-step explanation:
forluma:
(n-2)*180 degree
since octagon has 8 sides
(8-2)*180 degree
6*180
1080 degree
Answer:
Pair 2.
Step-by-step explanation:
For the volumes to be the same the base areas must also be the same.
For Pair 2 the areas are 25π and 24π while the other 2 pairs have both base areas = 25π.
You change 1/3 and 3/4 so that they have the same denominator.
The GCF is 12 in this case.
1/3 x 4 = 4/12
3/4 x 3 = 9/12
4/12 + 9/12 = 13/12 or 1 1/12 (One and one twelfth)
Hope this helped !!
Answer:
Step-by-step explanation:
If A is parallel to B, then angles 2 and 4 are same side interior and they are supplementary. Thus,
2x + 10 + 4x + 80 = 180 and
6x = 90 so
x = 15
