Question

is this triangle possible

sides with 3 cm 10 cm and 7 cm
angles are 60 degree 15 degree and 20 degree
give reason to support your answer.
pls tell.

Answer 1

no because sum of angles is not 180°

Plz mark it the brainliest if you find it useful

Answer 2

Firstly angle of triangle should180°
But here 60+15+20=95°
So triangle can't possible

And also two side sum should greater than middle but 7+3=10 it's equal so also triangle is not possible
