Answer:
i think 28 yards
Step-by-step explanation:
1. use pythagorean theorem to plug in variables.
b=77 yards → [tex]a^2+b^2=c^2[/tex]
c= 85 yards
[tex]a^2+ 77^2 = 85^2[/tex]
2. solve for a.
[tex]a^2+77^2=85^2[/tex]→[tex]a^2= 1296[/tex]→[tex]a=\sqrt{1296}[/tex]→[tex]a=36[/tex]
3. Add the a-value and the b-value.
36+77= 113
4. Subtract that by 85 yards.
113-85=28
