Answer:
m=0.7404, b=3.9117m=0.7404,b=3.9117
y=0.7404x+3.9117y=0.7404x+3.9117
x=18x=18
y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389

Answer:
Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve the problem.
tan θ = opp/adj
tan 30 = y/(4√3)
y = 4√3 tan 30
y = 4
