Answer:
x-4y = 8
Step-by-step explanation:
y– 1 =1/4 (x – 12)
Multiply each side by 4
4y -4 = x-12
Subtract x from each side
-x +4y -4 = -12
Add 4 to each side
-x+4y -4+4 = -12 +4
-x+4y = -8
Multiply by -1
x-4y = 8
Answer:maybe 9 but if not is 8 and the seond is 321
Step-by-step explanation:
Answer:
35/12
Step-by-step explanation:
The tangent in a triangle is always the opposite side divided by the adjacent side. In this triangle, BC is the side opposite to angle a, and AC is the side adjacent to angle A.
However, we do not know what AC is, but we can use the pythagorean theorem to solve. 
, which is 12 squared. Therefore, AC is 12 units in length.
Now we have all the sides of the triangle and we can divide the opposite side by the adjacent side. We get 35/12.
Hope this helps!
Answer:
2 = 67
3 = 113
4 = 67
5 = 113
6 = 67
7 = 113
8 = 67
Step-by-step explanation:
opposite angle have to equal 180 because if you combine them they just become the line.
since the lines are parallel, measurements will be the same for the bottom set of angles as they are the top set of angles.
Answer:
2.57
Step-by-step explanation:
10*10*10 = 1000
2570/1000 = 2.57
