Answer:
8
Step-by-step explanation:
The given equation can be rearranged:
4a -1 = a . . . . . . given
3a -1 = 0 . . . . . . subtract a
3a = 1 . . . . . . . . add 1
24a = 8 . . . . . . multiply by 8
Atio - 2: 3: 4 let them be 2x,3x, 4x
<span>total = 2x + 3x + 4x = 180 => 9x = 180 or x = 20 </span>
<span>so the angles are 40,60, and 80</span>
(-2,7) because of the circle equation.

I'm not super good at triangles, but I think it would be 20 yd^2, but I'm sorry I'm not totally sure
