Answer:
Hence the correct option is the last one . The triangle is an obtuse angled triangle.
Step-by-step explanation:
i) the sum of any two sides added together is greater than the third side hence this is a triangle.
ii) it is not a right angled triangle as [tex]\sqrt{9^{2} + 15^{2} } \neq 19[/tex] and [tex]\sqrt{9^{2} + 15^{2} } < 19[/tex]
iii) the triangle is not acute from ii) above
iv) the triangle is an obtuse triangle from ii) above.
