Answer:
A b c
Step-by-step explanation:
Your answer would be D or 6
Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72
Interest = (Principal X rate X time)/100
