Answer:
x ≈ 11.6 m
Step-by-step explanation:
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² + 10.7² = 15.8²
x² + 114.49 = 249.64 ( subtract 114.49 from both sides )
x² = 135.15 ( take square root of both sides )
x = [tex]\sqrt{135.15}[/tex] ≈ 11.6 m ( to the nearest tenth )
