Answer:
its B, 90
Step-by-step explanation:
thats a right triangle so the r angle is 90
There would be 868 steps. since there is 245 MORE steps in castle be than in castle a, you would have to add 623 to 245
7x - 4y = -28
3x +4y = -12
Using the elimination method because y is already eliminated
10x = -40
So x = -4
Then plug the -4 into the first equation....
7(-4) - 4y = -28
-28 - 4y = -28
-4y = 0
y = 0
I got: -4,0
