Answer:
The value of y is 44.
Step-by-step explanation:
From your equation expressed the equation is probably 56 = y - 12
56 = y - 12 Add 12 to both sides to isolate the variable
44 = y
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY</em></u> one side of the equation.

Sine (33) = BD / BC
BD = sine (33) * BC
BD = 0.54464 * 110

Perimeter = AB + BC + AD + DC
Perimeter = 84.73 + 110 + 59.91 + 92.25
Perimeter = 346.89
