Answer:

  • x = 56.9°

Step-by-step explanation:

Solving #2 in steps below

1) Find BC

  • sin 62° = BC/AC
  • 0.88 = BC/30
  • BC = 30*0.88
  • BC = 26.4

2) Find BD

  • cos 20° = BD/BC
  • 0.93 = BD/26.4
  • BD = 0.93*26.4
  • BD = 24.55

3) Find x

  • tan x = BD/DE
  • tan x = 24.55/16
  • tan x = 1.534375
  • x = arctan 1.534375
  • x = 56.9°
