Question

The angles of a triangle are in the ratio 4 : 5 : 11. The triangle is

Answer 1

Answer:

Sum of all angles in a triangle=180

Ratio of angle =4:5:11

=4+5+11=20

1st angle=4/20×180

=4×9

=36°

2nd angle=5/20×180

=5×9

=45°

3rd angle=11/20×180

=11×9

=99°

Therefore,the angles of the triangle are 36°,45°and 99°.
