Answer:

x ≈ 3.5 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin23° = \frac{opposite}{hypotenuse} = \frac{x}{y} = \frac{x}{9} ( multiply both sides by 9 )

9 × sin23° = x , then

x ≈ 3.5 cm ( to 1 dec. place )

The answer is 112 centimeters.

As this problem represents a right triangle, here we need to apply the Pythagorean Theorem.

  • h = √113² - 15²
  • h = √12769 - 225
  • h = √12544
  • h = 112 centimeters
