Answer:
4√6
Explanation:
because one of the angles is given to be 90 deg, the triangle is a right triangle. hence we can use the Pythagorean formula to find the 3rd side
(see attached for reference)
let the missing side be x.
We are given the length of the other side is 2 and the hypotenuse is 10
applying the pythagorean formula:
x² + 2² = 10²
x² + 4 = 100
x² = 100 - 4
x² = 96
x = √96
x = √(16 x 6)
x = √16 √6
x = 4√6
