Answer:

  • x ≈ 1.64 m
  • y ≈ 3.09 m

Step-by-step explanation:

  • ABC is right triangle
  • Angle A and side AB given
  • Side BC to be found

Use sine of A to find the length of missing side:

  • opposite/hypotenuse = sin
  • BC/AB = sin A
  • x/3.5 = sin 28
  • x = 3.5* sin 28
  • x = 3.5*0.47 ≈ 1.64 m

Horizontal distance y is:

  • y = √3.5²-1.64²= √9.5604 = 3.09 m
