Step-by-step explanation:

  • Question 1

The 20° angle is equal to the angle next you friend.

since they are interior alternate angles

The height of the ballon is 600 feet

Let x be the missing distance we are looking for

  • sin20° = 600/x            switch x and sin 20°
  • x = 600/ sin 20°
  • x=1754.28≈ 1754 ft

so the missing distance is 1754 feet

  • Question 2

Here I represented the situation to visualize the problem

Let h be L be the length of the ladder

  • sin 30° = 7/L          switch L and sin 30°
  • L= 7/sin 30° = 14
  • L = 14 ft

so the ladder is 14 ft
