Wich set of angles measure could be the measure of the interior angles of a triangle? 90,42 and 58. 60,60 and 60. 100,48 and 43.
4vir4ik [10]

Answer:

60°,60° and 60°.

Step-by-step explanation:

The sum of the interior angle of a triangle

=180°

So, let us test measured sets to get which of them could be the interior angles of a triangle.

The sum of the first measured set

= 90° + 42° + 58°

=190°

Also, the sum of the second measured set

= 60°+ 60° + 60°

=180°

The sum of the third measured set,

= 100°+ 48° + 43°

=191°

Finally, the sum of the fourth measured set

= 31° + 75°+ 70°

=176°

We can clearly conclude that, the measured set 60°,60°and 60° could only be the the set of interior angles of a triangle. Since it is the only set that add up to 180°
