Answer:
Right angle
Step-by-step explanation: you take the 57% angle and ad that with
the 33% angle and you got a prefect 90% also known as a "Right angle"
<span>ax + by + c = 0
by = - ax - c
y = -a/b (x) - c/b
so slope = </span>-a/b
answer
-a/b
L (water level) = -0.5 d (days) +34
Place 26 into the (L) variable and solve
26= -0.5 d + 34
0.5 d = 8
d=16
