Question

4, x and 9 are sides of an obtuse triangle. Find the number of integral values x can take?​

Answer 1

Answer:

let another side be x

we know that sum of all sides of triangle is 180

4x+9+x =180

5x+9 =180

5x = 180-9

5x= 171

x= 34.2.

CHECK:

4×34.2+9+34.2=180

136.8+9+34.2=180

171.0+9=180

180=180
