A, C

Step-by-step explanation:

hypotenuse (longest) cannot be more than the adjacent (shortest) + the opposite (2nd shortest)

1 < BC < 3

Step-by-step explanation:

like I said, the hypotenuse cannot be more than the adjacent plus the opposite, so the longest BC can go is 3 because 4 goes over 12 (9+4 is over 12)

ryan had a head start of 10 meters.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
