Alright, lets get started.
The length of each section what carpenter needs to cut is 3 feet and 8 inches.
Converting 3 feet and 8 inches into feet only, we know, 
So, 3 feet 8 inches =
feet
It means length of each section =
feet
Carpenter needs to cut 4 sections, so length of 4 sections will be = 
2/3 feet means 8 inches so she needs board 14 feet 8 inches
Board is only sold by the feet only so, she has to puchase 15 feet board. : Answer
Hope it will help :)
<span>Subtract 55 from 180 total degrees of a triangle to get 125.
Put 2x and x + 10 together...
3x + 10 = 125
Subtract 10 from both sides...
3x = 115
Divide by 3...
x = 38.3333
Now to find the measure of angle 2...
38.333(2) = 76.66666
Don't know if that's a multiple choice question or not, but that's what I got</span>
