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
Hope this helps!
Answer: Circumference = 25.12
Explanation:
Circumference = pi x d
C = 3.14 x 8
C = 25.12
Answer: Hi there, the answer should be the third option v < -8.
30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.
