Trigonometry question worth 100 points! desperately need help

Mathematics
1 answer:
Gala2k [10]2 years ago
5 0

Answer:

Height is 40√2 m or 56.57 m

Explanation:

Use Pythagoras theorem: a² + b² = c²

where 'a' and 'b' are the legs and 'c' is the hypotenuse

Here given:

  • a = 20 meter
  • b = height
  • c = 60 meter

Substitute values:

(20)² + (h)² = 60²

400 + h² = 3600

h² = 3600 - 400

h² = 3200

h = √3200

h = 40√2

h = 56.6 meter
