Answer:
h ≈ 3.9
Step-by-step explanation:
Using the right triangle with hypotenuse 4
Use Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
h² + 1² = 4²
h² + 1 = 16 ( subtract 1 from both sides )
h² = 15 ( take the square root of both sides )
h = [tex]\sqrt{15}[/tex] ≈ 3.9 ( to the nearest tenth )
