Answer:
A) $23.41
Step-by-step explanation:
you would multiply 57.10 by 41%
Start with the small triangle on the right:
35 + 96 + x = 180
x = 49
Ah, you already have that. Nice!
Now move to the biggest triangle:
x + 77 + (35+y) = 180
but x = 49, so
49 + 77 + 35+y = 180
y = 19
-3 is the increasing interval
