Answer:
C: 124
Step-by-step explanation:
If you look at the angle it has to be over 90 degrees so therefore your only option is C: 124.
Wel its kinda difficult to say but look on how much times 6 can fit into 7 which is 1 but that will be 6,so in order to become seven you need 1 which is our left over number,so in the end you will get 1 whole and 1/6 and you use the leftover number as your numerator and just leave the 6 as it was.Whoof that was long but its no nearly as long as i explain it.
Solve the lower equation first
+12 on each side
7x=51
divide by 7
x=51/7
then use that to solve the upper equation
