Where is the table? I need to see a table to give the answer
This is a chord, chord angle problem.
Angle 1 = (50 + 56)/2. This leads to 53 degrees.
Answer:
1/4 of the work
Step-by-step explanation:
A quarter (1/4) of the work is done in 2 days. Let's break it down:
Work can be finished in 8 days total so with 2 days it is only partially completed. If we set it up as 2/8 we can simplify to get 1/4. Therefore, we know only a quarter of the work is done so far.

Answer C.
5s + 5l = 155, 10s + 12l = 346
Solve for s in the first equation.
5s = 155 - 5l
s = 31 - l
Substitute s into the second equation.
10(31 - l) + 12l = 346
310 - 10l + 12l = 346
310 + 2l = 346
2l = 36
l = 18
Substitute l into the first equation.
5s + 5(18) = 155
5s + 90 = 155
5s = 65
s = 13
s = 13, l = 18
