Answer:
85° and 95°
Step-by-step explanation:
So, one angle is x, the other angle is x + 10. Using this, you can form an equation.
x + x + 10 = 180
Now, solve the equation.
2x + 10 = 180
2x = 170
x = 85
So, one angle is 85 while the other angle is 95.
85 + 95 = 180,
so we know that our answer is correct.
x-2
Since Tyler didn't start until Serena had wrapped 2 boxes and they both wrap boxes at the same rate, this could be written as x-2. This works for the second and third images if you plug in the number of boxes Serena has graphed for x in the equation. 3-2=1, 4-2=2.
