Angle 1 = 128
Angle 2 = 64
Angle 3 = 64
If you'd like an explanation, let me know!
Hope this helps!! :)
A(1) = 6 = d + c
<span>a(4) = 33 = 4d + c </span>
<span>3d = 27=> d=9 </span>
<span>c = -3 </span>
<span>a(2) = 9(2) - 3 = 15 </span>
<span>a(3) = 15 + 9 = 24</span>
You can start by writing equations with the given information
1) You know that together, Mindy and Troy ate 9, so you can write
M+T=9
2) Then, it says that Mindy ate 3, so M=3
3) Troy ate 1/4 of the total cake, however we don't know what the amount of the total cake is, so we can represent it as x, T=1/4x
4) Plug in these equations into the first equation, 3+1/4x=9
5) Solve for X, Subtract 3 from both sides to get 1/4x=6
6) Divide 1/4 on both sides, x=(6÷1/4)
x=24

120.25 I just divided the figure into smaller shapes, found the value and then I added the areas together! :)
Answer:
12x+4
Step-by-step explanation:
For the perimeter, we have to add up all sides of the triangle.
(3x-4) + (4x+5) + (5x+3)
3x-4+4x+5+5x+3
(3x+4x+5x) + (-4+5+3)
12x+4
