To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².
<span>Given
Side (A) = 10 in Side (B) = 8 in Side (C) = unknown
</span><span>The length of the third side must be greater than 0 but less than 18in </span> <span>10-8 < s < 10+8
2 < s < 18 </span><span> 17 in is the correct answer
