Answer:
missing side length ≈ 6.5
Step-by-step explanation:
Using the Pythagorean Theorem in the right triangle
• a² + b² = c² ( c is the hypotenuse and a, b the legs )
let a = missing side, b = 3.6 and c = 7.4 , then
a² + 3.6² = 7.4²
a² + 12.96 = 54.76 ( subtract 12.96 from both sides )
a² = 41.8 ( ta ke square root of both sides )
[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{41.8}[/tex]
a ≈ 6.5 ( to the nearest tenth )
