In triangle ABC, <A + <B +<C = 180
plug in
3x + 7 + 2x - 8 + 5 - x = 180
4x + 4 = 180
4x = 176
x = 44
Answer
x = 44
3/7 - 2/5 =
15/35 - 14/35 =
1/35 <==
Answer:
x = 2
Step-by-step explanation:
All the red lines tell you that each side must be equivalent because the angles are aka equilateral triangle.
So, 2x+4 = 8
2x = 8-4
2x = 4
2x/2 = 4/2
x = 2
