Answer:
∠2 = 115.5°
Step-by-step explanation:
128.5° is an exterior angle of the triangle
The exterior angle equals the sum of the 2 opposite interior angles, hence
∠2 + 13 = 128.5 ( subtract 13 from both sides )
∠2 = 115.5°
will she would have rode 4 3/5 miles in all.
2 3/10+2 3/10=4 3/5
that is 2 3/10 there and 2 3/10 back so you would add that together.
MILES IN ALL 4 3/5
Hope this helps
