Question

What’s the missing leg length round to nearest tenth if needed

Answer 1

b = √19 meters ⇒ ( About ) 4.4

Explanation:

Knowing that this is a right triangle;

a^2 + b^2 = c^2 ⇒ Applying Pythagorean Theorem, where a and b are the legs, c ⇒ hypotenuse,

9^2 + b^2 = 10^2 ⇒ Solve for value of b,

81 + b^2 = 100 ⇒ Subtract 81 from either side,

b^2 = 19 ⇒ Take square root of 19,

Solution; b = √19 meters
