Every triangle measures 180 degrees.
In order to get the answer you need to add every equation and set it equal to 180.
2x+4+2x-9+x=180
Combine like terms.
5x-5=180
Add 5 to the other side.
5x=185
Divide by 5.
x = 37
Now, plug 37 in for every x.
Angle A: 2(37)-9
Angle B: 2(37)+4
Angle C: 37
The measures are:
Angle A = 65
Angle B = 78
Angle C = 37

Answer:
y=4
Step-by-step explanation:
I'm a little rusty at this but y=4 should be the correct answer.
Hope this helps!
The answer to Part A is 2 15/32
1. y=4x
2. y=-7x-8
3. y=5x+63
4. y=¾x+8
5. y=-3x-½
6. y=1x-3
7. y=2
8. y=-2x+1
9. y=4x+7
wor<u>k for 9</u>
1=4(2)+b
1= 8 +b
-8 -8
7=b
10. y=0
11. y=¾x+6

Answer:
You are a rectangular prism.
Step-by-step explanation:
Rectangular prisms fill the criteria you described: two triangular faces, three rectangular faces, 6 vertices, and 9 edges. Thus, the answer is correct.
