So Angle x is actually the same as angle BCA
So what you have to do is get that first
41+102+x=180
x=37
That is due to BAC and BCA being AIA (alternate interior angles)
To get the answer we have to find number of towers.
If Arturo built 3 sandcastles with 6 towers each we can say that Arturo built
3*6=18 towers
If Paco built 5 sandcastles with 4 towers each we can say that Paco built
5*4=20 towers
20-18=2 - difference between Paco and Arturo
Answer:Arturo made more towers. The difference is 2.
Answer:
The fourth term in the sequence is equal to the third term plus the common difference, or 16+3=19- last choice
3x+y=19
y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:
19-3x=x+3
19-4x=3
-4x=-16
x=4, and since y=x+3
y=7 so the solution is the point:
(4,7)
The best answer to your question is 'D'
