3(d + 11) = 6(d + 33)
So you have: 3d + 33 = 6d + 198
which is: -3d = 165
or d = -55
So you have <em>only one answer.</em>
Answer: Step-by-step explanation:
angle 1=41°
angle 2=angle 1=41°
angle 3=180-2×41=98
D is the correct answer
x+5=10: subtract 5 from both sides the 5 will cancel out leaving x=5
x+5=10
-5 -5
x=5
