Step-by-step explanation:
I'll be using substitution to solve this since it's easier. Since y = 3x - 9, I can plug that into the y for the other equation and vice versa.
1.) Cancel out -2x on the right side by adding it on both sides.
2.) Cancel out -9 on left side by adding it on both sides.
3.) Divide both sides by 5 to isolate and solve for x.
4.) Plug x into one of the equations to solve for y.
5.) Solve.
Solution: (2, -3)
Using the law of the sine we have:
x / sine (m∠Y) = 25 / sine (m∠X)
Where,
m∠Y = 180 - m∠X - m∠Z
m∠Y = 180 - 38 - 67
m∠Y = 75
Substituting values:
x / sine (75) = 25 / sine (38)
Rewriting we have:
x = (25 / sine (38)) * (sine (75))
x = 39.22309033
Round to the nearest tenth
x = 39.2 feet
