Since they are both degrees of an angle they would be equal:

3x+80 = 7x-40

80 = 4x-40

120 = 4x

x = 120/4 = 30 degrees

7x-40 represents the central angle, the arc 3x+80 equals the central angle, it is the same, so 7x-40=3x+80. 7x-3x=80+40. 4x=120. X=30. Let’s plug it in. This can be a way to check the answer. We get: angle=170 and arc=170. So x=30 is correct.

P=2L+2W
We know that L=26, W=21
so
Perimeter, P = 2(26)+2(21) = 52 + 42 = 94 feet

Three sections of a fence need to be painted. Each section of the fence is made of 4 equal-sized boards. Alex paints 1/6 of the
zepelin [54]
Part A:

Total boards = 3 sections of 4 boards = 12 boards

Alex paints: 1/6 of 12 boards = 2 boards

Bobby paints: 2 x Alex = 1/3 of 12 boards = 4 boards

Charles paints: 1 board

David paints: 12 - (Alex + Bobby + Charles) = 12 - 7 = 5 boards

-This means that David painted the largest part of the fence

Part B:

The fraction of the fence that David painted = 5 boards /12 total boards = 5/12
